PANTHER
(4/98) 1-1
1 Introduction
This manual describes basic programming, operation, and service techniques
for the PANTHER Analog and Digital Industrial Scale Terminal, a high
performance basic capability weighing instrument. The PANTHER has been
designed to meet the needs of simple weight indicating applications, over/under
manual checkweighing applications, and high speed batch processing
applications.
PANTHER
Terminal Overview
Ease-of-Installation
Multi-Voltage Power Supply - The PANTHER® Terminal uses a manually
selectable universal power supply which can be used with 100,120, or
220/240 VAC sources, meeting global requirements. The harsh enclosure unit
is shipped with an integral power cord and the appropriate plug for the installing
location, provided the appropriate country finish code was used at the time of
ordering. The panel mount units are shipped without a power cord since panel
installations vary so widely. A terminal strip is used for power connection,
providing the flexibility to tie into a power strip or power terminal block wherever
it may be located within or outside of the enclosure.
Simple Mounting - The Panel Mount PANTHER® requires only a simple
rectangular panel cutout and the drilling of four mounting holes. The Harsh
Environment (Desk/Wall) PANTHER uses cord grips for quick cable installation
and sealing. The bracket included allows you to place the PANTHER Terminal
on a desktop, mount it to a wall or be attached to a Mettler Toledo column.
Terminal Strip Connections - All wiring terminations are made to terminal strips.
All connections are clearly marked for load cell, discrete input/output, serial
output, and power termination.
Reliability
ISO 9001 Quality - The PANTHER® Terminal was developed, produced, and
tested in a Mettler Toledo facility that has been audited and registered according
to international ISO 9001 quality standards.
Factory Assembly - The PANTHER® Terminal can be factory assembled to any
available combination of standard and optional features. Factory assembled
models will be tested as a system, including all internal functions and external
I/O, and shipped ready for installation “out of the box.”
Performance Standards - The PANTHER® is designed to meet all international
weights and measures and electrical safety standards. It has high immunity to
external influences such as radio frequency, electromagnetic interference and
static discharge.

Power Requirements
The PANTHER Terminal is provided with a universal power supply which
operates from 85 to 264 VAC. The supply operate with a line frequency of 49 to
63 Hz. Power consumption is 12 Watts maximum. Power is applied through a
terminal strip. The power cord is not provided with the panel mount version
(PTPN).
The integrity of the power ground for equipment is important for both safety and
dependable operation of the PANTHER Terminal and its associated scale base.
It is important that equipment does not share power lines with noise generating
equipment like heavy load switching, motor starter circuits, RF thermal heaters,
inductive loads and the like.
To confirm ground integrity, a commercial branch circuit analyzer like an ICE
model SureTest ST-1D (or equivalent) is recommended. This instrument uses a
high amperage pulse to check ground resistance. It measures the voltage from
the neutral wire to the ground connection and will provide an assessment of the
line loading. Instructions with the instrument gives guidelines about limits that
assure good connections. Visual inspections and a query of the user will
provide information about equipment sharing the power line.
The power line for the PANTHER must not be shared with equipment such as
motors, relays, or heaters that generate line noise. If adverse power conditions
exist, a dedicated power circuit or power line conditioner may be required.
Controller PCB
The PANTHER Terminal has one discrete input and three discrete outputs (5
Volts DC). Each discrete output can sink up to 20 mA maximum. The
maximum current that can be drawn from the +5 Volts DC supply is 15 mA.
The input for PANTHER Terminal is programmable as tare, print, zero, or unit
switching. Three outputs are used for setpoint coincidence and zero tolerance,
or over, under, or accept indication.
The PANTHER Terminal’s COM1 serial port is an RS-232 transmission port.
COM1 will also support receipt of an ASCII command set which will cause the
indicator to Clear, Tare, Zero, Print or change Units. COM1 can also be
configured as an SICS Host Interface port.
Connections to the Controller PCB are made using screw terminal strips. The
wire size range for these terminal strips are 24 to 16 AWG.
Display and Keyboard
The PANTHER Terminal Panel Mount model’s front panel is made of stainless
steel sealed to NEMA 4 (IP65) specifications. The Harsh Environment front
panel is fabricated stainless steel, and when locked onto the rear enclosure, is
sealed to NEMA 4X (IP65) specifications.
The display is a seven-character, seven-segment, 0.55 in. (12.7 mm) vacuum
fluorescent numeric display.
The keyboard consists of a flat membrane switch covered with a domed
polyester overlay.

Enclosures
Harsh Enclosure (HN). This enclosure provides NEMA 4X (IP65) protection. A
keyboard and display are standard. The enclosure is a fabricated stainless steel
box with a removable cover. The unit is designed to sit on a flat surface or can
be mounted to a wall or to Mettler Toledo columns. The bottom of the enclosure
contains grip bushings to seal all cables entering the enclosure.
Panel Enclosure (PN). This enclosure is designed to be mounted into a panel.
Four threaded studs are used to mount the unit through a flat panel. The front
panel and associated panel clamping mechanism are designed to provide a
NEMA 4 (IP65) seal and accommodate a panel thickness from 16 to 11
gauge.
Numeric Display. The PANTHER contains a seven-character, 0.55 in. (12.7
mm) high vacuum fluorescent display with a domed keyboard on a stainless
steel front housing. It can indicate weight values in standard use or display
recalled information, errors, and other messages. Each digit has a decimal
point/comma and an annunciator. The annunciators indicate gross or net
weights, center of zero, and weight units. The universal keyboard has symbols
for Memory, Tare, Select, Clear, Zero, Enter/Print, and Function. These keys
allow access to operator prompting, setup, and other functions.
The harsh enclosure version includes five multi-colored LEDs used to indicate
over or under tolerance conditions for manual checkweighing applications. In
setpoint applications, these LEDs indicate the status of the individual setpoints.
The panel mount version includes three LEDs which indicate similar conditions.
Accessories
Analog Output. The PANTHER Terminal offers an optional Analog Output port for
output ranges of 4 to 20 mA or 0 to 10 VDC, plus a status indicator. This output
uses a 16 bit D/A converter for a very precise output. The output status is an
optically isolated, open collector type with a 30 volt maximum limit. The Analog
option can be installed in either enclosure style, but is not available when the
PANTHER Terminal is used with more than four analog load cells.
High Level Discrete Output. The High Level Discrete Output option provides
high level AC interfacing (28 to 280 VAC) for use with the standard low level
discrete outputs. Three output blocks can be installed on the rear of the panel
enclosure. AC connections are made via terminal strips on the rear panel. Other
versions of output blocks can be installed to control DC voltage rather than AC
voltage. The high level discrete output is available only for the panel enclosure.
Allen-BradleyÔ PLC Connectivity. An option is available for the PANTHER
Terminal to enable the terminal to operate as a standard A-B PLC remote I/O
device. Integration of a PANTHER Terminal with an A-B PLC system is as simple
as making the “blue hose” connection and communicating with the terminals
directly from your PLC program.
PROFIBUSÔ Connectivity. The PROFIBUS interface module directly interfaces
with PROFIBUS devices such as PLCs manufactured by Siemens and Texas
Instruments. This direct connection allows for transfer of scale-related
Chapter 1: Introduction
Capacity and Increment Size
(4/98) 1-13
information to controlling devices at speeds up to 12 Mbaud. The PANTHER
Terminal is an L2-DP device, fully certified by the PROFIBUS Test Center.
Modbus™ Plus Connectivity. The Modbus™ Plus interface allows interfacing to
a Modbus Plus network. Modbus Plus is a local area network designed for
industrial control applications. It enables Modicon Model 984 programmable
controllers, host computers, Jaguars, PANTHER Terminals, and other devices to
communicate throughout the production areas of an industrial plant. It supports
64 addressable node devices at a data transfer rate of 1 Mbaud. Up to 32
devices can connect directly to a network cable with a length up to1500 feet.

The PANTHER Harsh Environment model uses four spring clips to lock the front
panel in place and seal the enclosure to NEMA 4X specifications. These clips are
attached to the enclosure body. To access the Controller PCB for internal wiring
and setting switches:
· Separate the front panel from the enclosure.
· Insert the tip of a flat-blade screwdriver into one of the three slots located on
the bottom of the front panel assembly and gently push in toward the
enclosure. You should hear a quiet “pop” when the cover has been released.
· Push in on the side of the slot closest to the bottom of the cover.
· Repeat for the other slots.
· After releasing the front panel, lift the bottom of the front panel out until it
completely clears the enclosure.
· Squeeze the top of the front panel to the enclosure slightly and raise it to clear
the two top clips. The cover will swing down hinged by a wire cable at the
bottom. Figure 2-1 shows the location of the slots (A).

To connect the unit:
· Pass the cables that enter the enclosure through an appropriately sized cable
grip before connecting the wires.
· Tighten the cable grip sufficiently to provide a water-tight seal around the
cable only after re-securing the back cover. This will allow any internal cable
slack to be received through the cable grip.
Opening the Panel

Minimum Increment
Size for Analog Scale
Input
The minimum increment size selection for an analog scale input is determined by
calculating the microvolts per increment for the desired build.
METTLER TOLEDO PANTHER Terminal Service Manual
2-8 (4/98)
To calculate the microvolts per increment, solve the following equation for mV per
increment.
Increment Size ´ cell output ´ 5000
mV per Increment = ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ
Load Cell Capacity ´ Ratio
The increment size, scale capacity, and load cell capacity must all be measured
in the same weight units, lb or kg. If the weight units for any of these variables
are listed in kg units, multiply by 2.2046 to convert to lb units for the purposes of
this calculation.
Load cell output is rated in mV/V (millivolts per volt of excitation), marked on load
cell data tag. Mettler Toledo load cells are typically 2 mV/V. Other load cells can
range from 1 mV/V to 4.5 mV/V.
The load cell capacity is the rated capacity marked on load cell data tag. The
ratio is the total number of load cells in the system or the total lever ratio (if scale
is a mechanical lever system conversion).
Sample Calculation
1. Refer to the following example of mV per increment calculation for a Model
2158 floor scale installation.
Scale Capacity 5000 lb
Increment Size 1.0 lb
Load Cell Capacity 2500 lb
Number of Cells 4
 

Cell Output2 mV/V
Excitation Voltage5 VDC

2. Use the following formula to calculate the mV per increment:
Increment Size ´ cell output ´ excitation (mV)
mV per Increment = ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ-
Load Cell Capacity ´ Ratio
Substituting the 2158 parameters in the formula:
1.0 lb ´ 2 mV / V ´5000
mV per Increment = ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ = 1.0mV/inc.
2500 lb ´4 load cells
The PANTHER Terminal is approved as legal-for-trade at a minimum of 1 µV per
increment. Acceptable weighing performance for non-legal-for-trade applications
can be obtained when a minimum of 0.6 µV per increment is provided. At full
scale, the maximum load cell output may not exceed 10 mV in the 2 mV/V
jumper position or 15 mV in the 3 mV/V jumper position.

General
Information
The Panther setup parameters are divided into seven program blocks. Each
program block is divided into sub-blocks where you select and configure
individual operating parameters. This chapter describes each program block and
sub-block in detail. You should read through this chapter and configure each
parameter before you begin using the Panther indicator.
The Panther program blocks use several standard conventions. This section gives
general information on keystroke functions, navigation procedures, and program
block access and exit.
Keystroke Functions
The following keys are used to configure the program blocks.
ZERO Backup to the previous step.
TARE Moves the blinking edit cursor left one digit.
CLEAR resets a numeric data entry value to zero and/or allows programmer to
skip to the end of setup.
MEMORY moves the blinking edit cursor right one digit.
SELECT increments the numeric data entry digit and/or allows the programmer to
view the next in a selection list.
ENTER Accepts/terminates a data entry.
Program Block Access
In order to configure the program blocks the programmer must enter the setup
mode. Open the Panther terminal as described in chapter two of this manual and
close SW1-1. Close the terminal and press the ENTER and ZERO keys
simultaneously.
Note: the setup switch can remain
closed if terminal security is not
required.
Chapter 3: Programming and Configuration
General Information
(4/98) 3-3
General Programming
Procedure
After accessing the setup mode, each program block and sub-block can be
configured according to the procedure outlined in the following pages. If the
Panther terminal is being configured for the first time it is recommended that the
programmer configure each program block to assure the terminal is setup
correctly as the application and/or environment dictates.
Once the F1 prompt is displayed the SELECT key will skip to the next block and
the ENTER key will enter the block.
Once ENTER is pressed the Panther advances to the first parameter in the block.
The display shows the sub-block number and the current value setting. Press
ENTER to accept the value and advance to the next sub-block or press the
SELECT key to toggle through the choices until the desired selection is displayed.
After the desired selection is displayed press the ENTER key to accept the value.
Continue this procedure throughout the setup routine until all changes required
have been made.
Program Block Exit
To exit setup press the CLEAR key to advance to the CALOFF display. Next, press
the ENTER key. The Panther terminal will exit setup and return to the normal
operation mode. At this point, the switch S1-1 can be turned off to secure the
terminal.
The following sections describe each program block.

The PANTHER Terminal provides a wide selection of primary and alternate weight
units. Primary units is selected in Step F1.2 as the Calibrated Unit. Alternate Units
is selected in Step F2.1. The two selections most commonly used are lb and kg.
If the primary and/or alternate weight unit selection is something other than lb or
kg, an adhesive overlay (shipped with the PANTHER Terminal) needs to be
installed over the "lb" or "kg" legend on the PANTHER Terminal display lens. This
will correctly identify the displayed weight when shown converted to this unit (t for
tons for example). The label should be applied as follows:
· If one of the selected units is lb, the overlay should be placed over "kg" on
the lens.
· If one of the selected units is kg, the overlay should be placed over "lb" on
the lens.
· If neither the primary or alternate unit is lb or kg, then the left cursor (lb
position) is used to indicate the primary unit and the right cursor (kg
position) is used to indicate the alternate unit.
Examples:
The Panther Terminal is calibrated
using pound test weights and is
switchable to ounces. Lb is the
primary unit and "oz" (ounces) is
the alternate unit. The "oz" overlay
would be placed over "kg" on the
PANTHER Terminal Display Lens.
The PANTHER Terminal is
calibrated using kg test weights
and is switchable to metric tons.
Kg is the primary unit and "ton"
(metric tons) is the alternate unit.
The "ton" overlay would be placed
over "lb" on the PANTHER Terminal
Display Lens.

Stability detection occurs over a predefined period of time and allows a
predetermined “acceptable” amount of motion (in scale increments).
If AZM=0, the tare and zero value
will be stored during a power loss.

The Zero key is used to compensate for small changes in weight when the scale
platform is empty. These changes in weight are most often caused by material
spilling onto the weighing platform. To zero the indication of weight, press this
button.
The Tare key is used to subtract the weight of the object on the scale platform
from subsequent indications of weight. This is most often the weight of an empty
container. Once this value is “tared,” the indication of weight will change to
indicate net weight. To tare the scale, place an empty container on the scale and
press this button.
The Clear key is used to clear a previously entered tare value. To clear the tare
value, press this button. The indication of weight will return to the gross mode,
showing the total weight of the objects on the scale platform.
The Memory key is used to access setpoint or target weight values. Operator
access to these values must be enabled in the set up mode. Refer to the
advanced operation section for details on how to change these values.
The Select key allows the operator to switch between the primary and secondary
weighing units. To change weighing units, press this button. Each initiation of
this button will either switch the display units from the primary to the secondary
units, or back to the primary from the secondary. A cursor will change indicating
which units are being displayed. This key is also used in the setup and
programming modes to select between yes and no replies and to change
displayed values.
The Transact (Print) key is used to initiate a serial output of the weight data. To
request this transmission of data, press this button. The actual format of the data
string is determined in set-up. This key is also used to accept a response to a
setup or programming question.

Operations
Entry of Setpoint Data
During Normal
Operation
The Panther Terminal is provided with the capability of two coincidence setpoints
with preact control. While setpoint values are always entered as positive values,
the controls can be set up to turn outputs off when either a positive value (feeding
Chapter 4: Panther Keypad
Advanced Scale Operations
(4/98) 4-3
into something on the scale) or a negative weight value (discharging from the
scale into a container). The setpoint control may be used with optional high level
outputs available with the Panther Panel Mount versions. These high level
outputs may be used in conjunction with external devices that may be provided
by other parties.
A setpoint is a target value that you may wish to use to stop a feeding or
discharging device. When the weight on the scale exceeds the setpoint value, the
setpoint output is turned off. In addition to the setpoint values, the Panther
provides the ability to enter and use preact values. Preact is used to anticipate
the amount of material which may be between the feeder and the scale when the
feeder is turned off, or may be used to anticipate the reaction time of the feeder or
gate. A zero tolerance value is also available. This can be used as a control
check to make sure the hopper or scale has returned to within a preset tolerance
of zero before the next operation may begin.
The setpoint mode of operation must be enabled during setup (refer to the
Technical Manual for details).

Preact is the amount of material which may be in suspension immediately after a
signal to close or turn off a feeder is sent. The preact amount is entered as a
value relative to the setpoint. For example, if you wish to have a final weight on
the scale of 100 kg, and the material which will fall from the feeder as it stops will
add another 2 kg, set your preact value for 2. When the material settles on the
scale, the final weight should be 100 kg.

Entry of Target
Over/Under Values
During Normal Operation
The Panther is designed as an “Over/Under” indicator. A series of LEDs indicate if
a weight on the scale platform is within acceptable tolerances of a target weight.
Four different target values may be stored and recalled by the operator.
“Over/Under” mode may be used with optional High Level outputs. Three output
“Over”, “OK”, and “Under” are available.
High and low accept zones may also be specified. These zones may be
determined as a percentage of the target value or as a number of increments of
weight as related to the target value. The high and low accept zones define the
acceptable tolerances around a target value. The high and low zones define the
point at which the item being checked is outside an acceptable tolerance around
a target weight. Setting of target values and tolerance values must be enabled
in the setup of the Panther.

METTLER TOLEDO PANTHER Terminal Service Manual
4-10 (4/98)
Zone Width Programming
If the Panther Terminal is used in the over/under mode, the zone width edges
must be determined and programmed into the Panther Terminal memory before
the status LED’s display will be usable.
To calculate the parameters entered into the zone programming group, (steps
F5.8.1, F5.8.2, F5.8.3, and F5.8.4) divide the desired zone width by the
increment size (programmed during calibration). The High Accept zone width
must be subtracted from the High zone width and the Low Accept zone width
must be subtracted from the Low zone width for the calculation to be correct.
Zone Width Programming
Example
The Panther Terminal is programmed for a scale capacity of 100 by 0.02 lb
increment size. The end user requests the following zone edges:
Over weight = 0.52 lb or more above the target weight
Highest High Accept weight = 0.50 lb above the target weight
Highest Accept weight = 0.30 lb above the target weight
Lowest Accept weight = 0.20 lb below the target weight
Lowest Low Accept weight = 0.40 lb below the target weight
Under weight = 0.42 lb or more below the target weight
High zone edge is equal to 10 divisions, (0.5 lb - 0.3 lb ) ÷ 0.02 lb
High Accept zone edge is equal to 15 divisions, 0.3 lb ÷ 0.02 lb
Low Accept zone edge is equal to 10 divisions, 0.2 lb ÷ 0.02 lb
Low zone edge is equal to 10 divisions, (0.4 lb - 0.2 lb) ÷ 0.02 lb
In other words, the Accept (OK) LED (middle red LED in the PN enclosure, or
green LED in the HN enclosure) will stay lit while the weight is less than or equal
to the target plus 0.30 lb and greater than or equal to the target minus 0.20 lb.
The Over OK LED (not available in the PN enclosure or upper yellow LED in the
HN enclosure) will light if the weight is greater than the target plus 0.30 lb and
less than or equal to the target plus 0.50 lb. The Under OK Led (not available in
the PN enclosure or lower yellow LED in the HN enclosure) will light if the weight
is less than the target minus 0.20 lb and greater than or equal to the target minus
0.40 lb. The Over LED (upper red LED in the PN and HN enclosures) will light if
the weight is greater than the target plus 0.50 lb. The Under LED (lower red LED
in the PN and HN enclosures) will light if the weight is less than the target minus
0.40 lb.
Zone Width as a Percent
of Target
To calculate the zone widths, when using percentage of target weight, setup step
[F5.7.1 1], remember that up to 4% of the programmed weight can be selected
for each of the zones. This means weight of up to 4% of the target weight can be
put on the platter before the yellow over accept LED (HN enclosure only) will turn
Chapter 4: Panther Keypad
Advanced Scale Operations
(4/98) 4-11
on. Add up to another 4% of the target weight, or 8% total, before the red over
LED will turn on. The same is true for the under LED’s.
Zone Width as a Percent
of Target Example
The scale is calibrated for 10 lb by 0.005 lb increment size. Each zone is set for
the full 4% of target weight. The operator places 2 lb on the platter and presses
the Tare key. The Accept (OK) range will be from 2 lb - (2 lb x 4%) to 2 lb + (2
lb x 4%). The Over OK range will be from 2 lb + (2 lb x 4%) + 0.005 lb to 2 lb
+ (2 lb x 8% or 4% + 4%). The Under OK range will be from 2 lb - (2 lb x 4%)
- 0.005 lb to 2 lb - (2 lb x 8 % or 4% + 4%).
The display reads (2.000) and the Accept (OK) LED is lit.
At 2.085 lb the Accept LED will turn off and the Over OK LED will turn on. At
2.165 lb the Over OK LED will turn off and the Over LED will turn on.
At 1.915 lb the Accept OK LED will turn off, and the under OK LED will turn on. At
1.835 lb, the Under OK LED will turn off and the Under LED will turn on.

Discrete Output Voltage
With no load applied and the PANTHER Terminal at gross zero, the following voltages
should be measured. Refer to the following table for correct voltage readings.
 

Test PointsVoltage Readings
GND & +5 VDC5 VDC*
+5 VDC & OUT15 VDC*
+5 VDC & OUT25 VDC*
+5 VDC & OUT35 VDC*

*If voltages are not within the +4.5 to +5.2 VDC range, check for:
· Check wiring. Refer to Chapter 10 Appendix, Discrete Outputs.
· Correct programming.
· Correct setpoint weight values. Refer to the section entitled MEMORY Key
Operations—Setpoints in Chapter 4.
RS232 Serial Output Test
Use the following test procedure to determine whether the RS-232 serial port is
operational.
1. Remove power from the PANTHER Terminal and the printer and disconnect the
data cable from the printer.
2. Set the volt meter to read 20 volts DC.
3. Connect the red lead to pin 2 of the printer end of the data cable and connect the
black lead to pin 7.
4. Apply power. The meter should read as follows:
· In Demand mode, the meter should read between -5 and -15 with no
fluctuation.
· In Continuous mode, the meter should fluctuate between -5 and +5
continuously. The constant fluctuation on the meter display indicates the
scale/indicator is transmitting information.
To test Demand baud rates, press the Transact (Print) key. The display should fluctuate
between -5 volts to +5 volts for the duration of the transmission, then become stable
again. This indicates the terminal has transmitted data.
Analog Output Option
Test the voltages of each output to ground. Depending on the calibration of the scale
and the displayed weight, each output should be outputting a linear voltage with
respect to calibration. If the voltages are not present or the error code repeats, replace
the analog output PCB.
When measuring the higher baud
rates in the Demand mode, the meter
display will fluctuate for a shorter
period of time.

Overview
In the "weight-synchronous" communications mode, the PANTHER Terminal
initiates a communication exchange with the PLC at every A-to-D weight update.
This mode is also known as the Discrete I/O mode in Allen-Bradley terminology.
The weight-synchronous communications is a high-speed, real-time message
interface between the PANTHER Terminal and PLC for process control.

Communications
The Allen-Bradley Remote I/O (RIO) network is an Allen-Bradley proprietary
network that permits certain A-B PLCs to communicate to additional racks of input
and output devices or to other peripheral devices that implement the RIO interface.
The network has evolved with generations of A-B PLCs to implement higher
speeds and more connections. The PANTHER Terminal utilizes component parts
that are provided by A-B thereby assuring complete compatibility with the RIO
Chapter 6: PANTHER Terminal Allen-Bradley Option
Communications
(4/98) 6-7
network. PANTHER Terminals are recognized as an Allen-Bradley device by the
PLC.
Each PANTHER Terminal connected to the RIO network represents a physical
node. The connection is facilitated by a three-position removable terminal block
on the PANTHER Terminal RIO Option back panel. The terminal block is labeled 1,
SHLD, and 2. These terminals correspond to the like terminals on the A-B PLC
RIO connector. The wiring between the PLC and the PANTHER Terminal RIO
connector uses the standard RIO cable supplied by Allen-Bradley. This cable is
often referred to as the "blue hose." The cable installation procedures and
specifications are the same as recommended by Allen-Bradley for the RIO
network.
Node Address
Although each PANTHER RIO Option represents one physical node, the
addressing of the node is defined as a logical rack address. This address is
determined by the system designer, then programmed into the PANTHER.
Programming is done through the Allen-Bradley program block in setup. Each
scale occupies a quarter rack in the RIO address space and the quarter may be
defined as the first, second, third, or fourth quarter of a rack. It is also necessary
to designate the location of the PLC which is the highest quarter used in a logical
rack. PANTHER programming capabilities allow selection of the starting quarter
and designation of the last rack.
Controlling PANTHER
Terminal Discrete I/O
using a PLC interface
The PANTHER provides the ability to directly control its discrete outputs and read
its discrete inputs via the (digital) PLC interface options. The PANTHER discrete
I/O updates are synchronized with the PANTHER A/D rate, not with the PLC I/O
scan rate. This may cause a noticeable delay in reading inputs or updating
outputs as observed from the PLC to real world signals."
Data Definition
The PANTHER RIO I/O network supports Discrete Data Transfer that allows for bidirectional communication of discrete bit encoded information or 16 bit binary
word (signed integer) numerical values. Each PANTHER represents a quarter rack
of data to the RIO Option and each quarter rack provides two input (read) and two
output (write) words. A quarter logical rack has 32 input bits (two 16 bit words)
and 32 output bits (two 16 bit words). The data in these input and output words
is formatted as follows:

PROFIBUS Overview

7 PANTHER Terminal PROFIBUS Option
Equipment installed in the field for the automation of technical processes is
increasingly using digital microelectronics. Bit serial Fieldbuses are being applied
for the communication between these digital field devices and higher level
automation components. Currently, a diversity of proprietary networks exists in
the Fieldbus area. The use of these networks often results in isolated incompatible
solutions. The need for an open, vendor independent communication system led
to the specification and standardization of PROFIBUS.
In any Fieldbus standard, many definitions are necessary in order to describe the
protocol completely and clearly. The result is a complex standard that seems to
be difficult to understand at first sight. Any technical questions about the
PROFIBUS Interface should be referred to the German national standard
PROFIBUS, DIN 19 245. Information is also available through the PROFIBUS User
Organization and on the World Wide Web.
PROFIBUS Overview
This section describes the option that permits the PANTHER Terminal to
communicate to a PROFIBUS L2-DP master according to DIN 19 245. The option
consists of a module and software that resides in the PANTHER Terminal, which
implements the data exchange.
The PANTHER Terminal PROFIBUS PCB interfaces to PLC’s such as, Texas
Instruments 505 series and Siemens S5-115 series PLCs.
The Texas Instruments (TI) 505 PLCs interface to the PROFIBUS via an I/O
processor called a Field Interface Module (FIM). The FIM bus master recognizes a
fixed set of PROFIBUS slave devices, all of which are viewed by it as some sort of
remote I/O rack. On power up, the FIM queries each PROFIBUS slave node to
determine which of the recognized types a device might be and configures itself
accordingly. The PANTHER PROFIBUS option appears to the FIM to be a small
ET200U I/O rack.
The Siemens S5-115 series PLC also interfaces to the PROFIBUS using an I/O
processor, an IM-308, which has no preconceived notions about PROFIBUS
devices. This device must be locally programmed with the PANTHER Interface
Device Data Base (DDB).
PROFIBUS Kit
Installation
The PANTHER Terminal PROFIBUS Option is available as a field installed kit by
ordering 0917-0252. The PANTHER Terminal 0917-0252 PROFIBUS Option Kit
provides connectivity to an PROFIBUS PLC using the remote I/O (RIO) protocol.
The PROFIBUS Kit may be installed in either the PANTHER Terminal Harsh
Environment or Panel Mount enclosure type. Included in the kit are the following

Wiring
The PROFIBUS connection is available at two locations on the PROFIBUS PCB. The
first is a female 9 pin D subminiature connector, which is the PROFIBUS standard
connection. The field connector assembly is not supplied by METTLER TOLEDO.
This connection is the preferred connection in PANTHER Panel Mount (PTPN). For
the PANTHER Harsh Environment (PTHN), the pluggable terminal strip must be
used. In these cases, a pigtail harness is available to wire from the terminal strip
to a female 9-pin D connector.

Modbus Plus Overview
(4/98) 8-1
8 PANTHER Terminal Modbus Plus Option
Modbus Plus
Overview
Modbus Plus is a local area network designed for industrial control applications.
The network enables Modicon Model 984 programmable controllers, host
computers, PANTHER Terminals, and other devices to communicate throughout
the production areas of an industrial plant. It supports 64 addressable node
devices at data transfer rates of one million bits per second. Up to 32 devices can
connect directly to a network cable with a length of up to 1500 feet.
The PANTHER Modbus Plus Interface is an option card that plugs into the
PANTHER. It has an 80C152 "Peer Processor" that implements the network
protocol; a 1K Dual Port RAM that is the data path to the PANTHER controller
card; an FM Encoder/Decoder; and an RS485 driver that provides the interface to
the Modbus Plus network.
The PANTHER is a single Modbus Plus node. Point-to-point communication in the
Modbus Plus network is the communication between two network nodes. The
"Master Task" at the initiating node generates a "transaction query" for the "Slave
Command Handler Task" at the destination node. The Slave Command Handler
Task sends a "transaction response" to the transaction query. Peer Processors
route the messages through the network. The Modicon 984 PLC acts as the
Master Task, and the PANTHER has the Slave Command Handler Task. The PLC
initiates all transactions, and the PANTHER responds to the transaction queries.
The general format for Modbus transaction query command is a one-byte
command followed by a group of bytes. The maximum length is 252 bytes. The
function bytes tell the slave device what action to perform.
The PANTHER supports the following Modbus functions:
03 Read Holding Registers. Requests the value of one or more 16-bit holding
registers.
16 Preset Multiple Registers. Places values into a series of consecutive holding
registers. The transaction query messages contain register values that specify
what data that the PLC is requesting from the PANTHER. For example, if the PLC
issues Function 03, the data field must contain information telling the PANTHER
which register to start at and how many registers to read. All address references
within the Modbus messages are relative to zero. For example, the first holding
register in the Modicon 984 PLC is 40001, but has the value 0000 in the
messages.

word (signed integer) numerical values.
On Modbus Plus, there are two words (32 bits) of input data for each scale and
two words of output data for each scale.
The Modicon PLC uses these holding registers assignments to request integer
weight and scale status from the PANTHER Terminal.

RS232 Serial I/O
The PANTHER will transmit RS232C serial data when a print command is issued
using the PRINT pushbutton, Auto Print, or a remote print command from a host.
The data format, baud rate, checksum, parity, etc. are selectable in the setup
mode. The serial data is output in an 10-bit ASCII frame which includes: 1 start
bit, 7 data bits, 1 parity bit, and 1 stop bit. Parity is selectable as none, odd, or
even using SSW F3.1.4. Checksum and STX can be enabled or disabled using
SSW F3.1.5 and F3.1.6. All demand mode printing is inhibited during motion and
when the weight is under gross zero. Printing is allowed on power-up whether or
not zero is captured if AZM is enabled (SSW F2.4.2). The available formats are:

METTLER TOLEDO PANTHER Terminal Service Manual
10-6 (4/98)
Appendix 2:
Standard Interface
Command Set
(SICS) Protocol
All new Mettler Toledo indicators support the standardized command set
“METTLER TOLEDO Standard Interface Command Set” (MT-SICS), which is divided
into 4 levels, depending on the functionality of the weighing instrument. The
PANTHER Terminal supports the MT-SICS level 0 command set.
What Do the Commands of MT-SICS Level 0 Offer?
You can use the commands of MT-SICS level 0 to perform the following
operations via the interface:
• Request weighing results,
• Tare the terminal,
• Zero the terminal,
• Identify MT-SICS implementation,
• Identify the terminal,
• Reset the terminal.
Additional Documentation on Data Interface
Settings of the interface such as baud rate, parity, and connector pin assignments
are described in previous sections of this manual.
Version number of the MT-SICS
Each level of the MT-SICS has its own version no. which can be requested with
the command I1.
This section describes: MT-SICS level 0, version 2.1x.
You can use the command I1 via the interface to request the MT-SICS level and
MT-SICS version implemented on the PANTHER Terminal.
Command Formats
Each command received by the PANTHER Terminal via the data interface is
acknowledged by a response of the PANTHER Terminal to the transmitter.
Commands and responses are data strings with a fixed format.
Commands sent to the balance comprise one or more characters of the ASCII
character set. Here, the following must be noted:
· Enter commands only in uppercase.
· The possible parameters of the command must be separated from one
another and from the command name by a space (ASCII 32 dec. in this
description represented as _ ).
· Each command must be closed by CR LF (ASCII 13 dec., 10 dec.)
The characters CR and LF, which can be inputted using the Enter or Return key of
most entry keypads, are not listed in this description, but it is essential they be
included for communications with the PANTHER Terminal.
Chapter 10: Appendices
Appendix 2: Standard Interface Command Set (SICS) Protocol
(4/98) 10-7
Response Formats
All responses sent by the PANTHER Terminal to the transmitter to acknowledge the
received command have one of the following formats:
• Response with weight value
• Response without weight value
• Error message
Format of the Response with Weight Value
A general description of the response with weight value is the following:
 

ID•••Status•••Weight Value•••UnitCRLF

Error messages
 

IDCRLF

ID--Error Identification
The PANTHER Terminal supports the following two error ID:.
• ES--Syntax error
The terminal does not recognize the command.
CR--Carriage return (ASCII 13 dec.)
LF--Line Feed (ASCII 10 dec.)
Tips for the Programmer. Command and Response---You can improve the
dependability of your application software by having your program evaluate the
response of the terminal to a command. The response is the acknowledgment
that the terminal has received the command.
Reset. To start from a determined state when establishing the communication
between terminal and system, you should send a reset command to the terminal.
When the terminal or system is switched on or off, faulty characters can be
received or sent.
Quotation Marks (“”). Quotation marks included in the command must always be
entered.
Commands and Responses MT-SICS Level 0
The PANTHER receives commands from the system computer and acknowledges
the command with an appropriate response. The following sections contain a
detailed description of all commands of the command set in alphabetical order
with the associated responses. Commands and responses are closed with CR
and LF. These termination characters are not shown in the following description,
but they must always be entered with commands or sent with responses.

Appendix 4:
Discrete Outputs
The outputs are +5 VDC. A solid state relay or OPTO 22 is typically connected to
buffer the outputs to a 120 or 220 volt AC signal. An output terminal supplies a 5
volt DC supply for reference to the setpoint outputs. Because the supply is rated at
115 mA of DC current, make sure the total current draw from the devices used
(relays or optos) do not exceed this limit. If the calculated current draw exceeds
115 mA, an external power supply is required. External power supplies are
available from your authorized Mettler Toledo representative.
The setpoint outputs are negative true and “ON” when the scale weight is below
the setpoint coincidence value. The setpoints operate on the absolute value of the
scale weight so they can be used for both weigh-in and weigh-out processes. The
following diagram shows a typical wiring scheme.
