Important Note
If the FG-200 acts as a visitor host, no comConf project must be downloaded into the FG-200
and the field devices.

§
Make sure Enable automatic VCR Creation is activated.
§
Activate or deactivate Link Master Functionality depending on the following presumptions:
For this scenario we recommend configuring the Node Address within the range from 252 to 255 for
the FG-200. If you want prevent the FG-200 to take an active role in the H1 segments, deactivate Link
Master Functionality . Usually this is not required if the H1 bus parameters used in the control system
are not too slow.
If
Link Master Functionality is activated make sure that all activated H1 links of the FG-200 are
connected to H1 segments with an active host system interface. Otherwise the FG-200 would wait for
a 6 minute period for activity on the H1 segments and would then disable the segments without
activity i.e. the segments without an active host interface.
5.1.3 Configuring the Modbus mapping table
The FG-200 supports the mapping of a set of function block parameters to Modbus registers. The set of
available parameters depends on the type of communication (PUB/SUB links or CLT/SRV connections) used
for transferring IO data.
The FG-200 selects PUB/SUB links or CLT/SRV connections depending on the downloaded comConf
project.
Perform mapping on the web server application
Prerequisite: You have downloaded the comConf project.
1. Open the web browser and login.
2. Go to

Devices.
4. Load the .csv file with the Modbus mapping. Select Configuration Modbus Mapping Import/Export .
Click [Import] and load the file generated by comConf.
Mapped values are now accessible in the configured Modbus registers and can be accessed by a Modbus
control.
5.1.4 Modbus statistics counter
You can get additional statistic information concerning the Modbus communication state by reading the
Modbus registers:
