READ this manual BEFORE operating or servicing this instrument. FOLLOW these
instructions carefully. SAVE this manual for future reference.
INTENDED USE
The G5 Instrument family are measuring and control devices intended for industrial
systems. Its basic function is to convert the signals from transducers to useful
information. Transducer excitation is included as well as parameter controlled signal
processing, indication of output levels, error supervision and operation of optional
external equipment. The instrument supports several types of communication
interfaces.
INSTRUMENT INSULATION AND GROUNDING
The cable connector for mains power supply should include protective grounding for
safety. The cable for 24VDC power supply (screw terminal connector) should include a
ground connected to terminal GND.
The input groups of the instrument are insulated from each other by functional
insulation. The mains connection of AC-powered instruments has reinforced insulation
according to IEC 61010. Terminals intended for connection of cable shields are
connected to the protective ground of the mains or GND terminal of 24VDC input but
must not be considered as protective grounding. Shield connection of load cell input is
not connected to mains protective ground or 24VDC GND terminal.

1. Introduction
General
The G5 Instruments are high performance single-channel weight indicators (PM model,
panel mounted) or weight transmitters (RM model, DIN rail mounted) intended for
industrial systems. This manual describes the functionality of the optional Fieldbus
interface of the G5 Instrument. The instrument supports the following busses:
ProfibusDP, DeviceNet, ControlNet and EtherNet/IP. The optional fieldbus module is
mounted in the Fieldbus slot.
l fieldbus settings are done with setup parameters in the instrument. No settings are
done on the module itself.
Module installation
Make sure the instrument power supply is off or disconnected. Remove the plastic
cover from the fieldbus slot. Insert the adaptor very carefully and make absolutely
sure that the adaptor slides correctly into the guidesin the connector on the PCB.
Tighten the two fastening screws at the adaptor front and check that the two securing
hooks locks into the PCB.

For reliable fieldbus function, line termination must be arranged in both ends of the
transmission line. For a G5 instrument, at the end of the cable, a connector with line
termination should be used. For all other G5 Instruments, connection without line
termination should be used.
For configuration of the adaptor, a GSD file (VISH0F83.GSD) is available and should
be installed in the master.
Select the 8 words output module + 2 x 16 words input modules + one 8 words input
module. This will give 16 bytes of output data and 80 bytes of input data. The PLC set-
up should match this exactly including the order of the input modules.

3. Set-up
General
All operating functions in the G5 Instrument are controlled by parameters. The
parameter values are permanently stored in the instrument and will not be lost when
the unit is switched off. At delivery the parameters are factory-set to default values,
giving the instrument an initial standard function.
The actual setting of the parameter values can be read and edited during normal
measuring operation in sub menu ‘Parameter Set-up’. Editing of parameter values can
be performed using the color display and keys on the front panel of the instrument or
by using a Web Browser on a PC connected on the same network as the instrument.
After editing hardware parameters the instrument will be restarted.
In the instrument there are two levels of security locks provided to protect from
unauthorized access to instrument functions and editing of parameters and values. The
locks are opened by four-digit codes.
Fieldbus related parameters
On the following pages a survey of fieldbus related parameters is presented. The
parameters are divided in groups following the menu they belong to. For choice
parameters the available choices are given. For numerical parameters, a value range is
given.
At the end of the table, the default value is given in < >.
To the right there is a short parameter explanation and, in italic, the results for
the different alternatives.

Command
Bytes 0 - 1: The command byte is used when writing data to the instrument and to
issue various scale related commands such as taring, zeroing etc.
Note that a new command is detected when the content of the command register is
changed. If the same command shall be issued again, the command byte must first be
set to 0 and this should be verified by reading command acknowledge. Then the
desired command may be issued.
The response to a given command is the ‘Command acknowledge’ and the
‘Command error’ bytes in the input data of the connection.
Parameter ID
Bytes 2 - 3: The selected Level (1 - 4) or Setpoint (1 - 4) to set. The data in byte 2 and
3 are ignored for any other commands than 221 and 222.
Data to write
Bytes 4 to 7: The value of the Preset tare, Level, Setpoint, Digital outputs or Analog
Output to set. Note that the format of the value should be floating point or integer
depending on the Data Format parameter. The data in bytes 4 to 7 are ignored for any
other commands than 200, 201, 220 – 222. No of decimals in an integer value is
according to the weight and flow rate set-up. Analog output (command 200) is always 3
decimals.
Example: A value with 3 decimals e.g. 7.234 should be written as 7234 to the
bytes 4 – 7.
Byte order
The byte order in multi byte values (more than one byte) is depending on the type of
fieldbus used.
Profibus DP: MSB first (Most Significant Byte first).
DeviceNet: MSB first.
ControlNet: MSB first.
EtherNet/IP: LSB first (Least Significant Byte first).

Instrument error
This register holds the overall error code for the instrument.
Normally this register should contain ‘00’ which means no error.
Instrument status
This register holds the overall status for the instrument
Bits set to 1 in this register have the following meaning:
Bit no Function Comment
0 Remote operation ‘1’ = On ‘0’ = Off
1 Program reset The bit is set each time the program starts, and it
indicates that volatile data is lost.
The bit is reset as Instrument status is read, over serial
communication (Modbus RTU) or over Ethernet (Modbus
TCP), for the first time after reset/power-up. Note that the
reply contains the set bit if it was set.
Reading Instrument Status via Fieldbus interface will not
reset this bit. To reset this bit with fieldbus interface a
specific reset command must be used.
Care must be taken if more than one interface is used to
communicate with the instrument and the Program reset
bit is to be used.

Instrument state
This register contains the state of the G5 instrument.
Code Description
00 ‘Starting up’ state.
The instrument is starting up after a reset or power on.
01 ‘Wait for start’ state.
The instrument is waiting for a start command to go in process.
02 ‘Warming up state’
The parameter ‘Warm up time’ is set to a value other than zero, and
the instrument is waiting for the warming up time to pass.
03 ‘Normal’ state.
There are no parameter errors in the system.
Note: Weight errors still indicate normal state.
04 ‘Error’ state.
An error has been detected during startup of the instrument.
05 ‘Fatal error’ state.
An error has been detected during startup of the instrument.
It’s not possible to enter any other state from here.
06 ‘Power fail’ state.
A power fail has been detected and the instrument will respond to
communication for a short moment until the power supply reserves are empty
(this is normally just a few ms). Weight values should be regarded as invalid.
Command acknowledge
This byte returns the value of the command if it could be executed. If there was an
error executing the command the value 240 (hex F0) will be returned in this byte. This
byte should be used to verify that a command has been executed.
Note that a new command is detected when the content of the command register is
changed. If the same command shall be issued again, the command byte must first be
set to 0 and this should be verified by reading command acknowledge. Then the
desired command may be issued.
