9.0 FIC Troubleshooting
If the Panel PC displays any issue then first make sure that the Data Pro hardware is working properly
by performing following check:

Both ribbon cables have good connections on the Main Interfacing board and the Panel PC.

The jumper on the Panel PC is at the correct position.

The LCD screen of the FIC is displaying the gauge data.

The connection from the FIC to Data Pro gauge port (Com 5) is good.
Perform a check on the placement of all jumpers on the Data Pro Main Interfacing board; reference
drawing is available in Appendix 3. The jumper for the
‘Watchdog’
remains at
‘disabled’
position while
other jumpers can be at different positions depending upon the customer application.
Troubleshooting Data Pro problems are grouped into two board categories.
Data Pro Gauge Data
– When any issue with the gauge data is observed, first check the gauge
‘Channel Information’
as discussed in section 7.3.5. The increasing number of packets in
‘Ch. Info’
indicates good communication whereas increasing number of repeats indicates the problematic
communication.
Then check the gauge connections to the DIN Rail terminal block and then check LCD of the FIC
module. The FIC module will show a
‘Gauge Dropout’
message whenever the gauge communication
is broken. The following features aretroubleshooting tools; they are discussed in detail in their
respective sections:

AutoVolt

Line Volt

Com Volt

Target Signal
Once communication between the gauge and the FIC module is established, then check the COM5 and
ribbon cable connections. Make sure that FIC is in the correct state to detect new gauge connections
and then rescan the FIC module. The Data Pro application will start displaying the gauge data on the
Panel PC screen once all the connections are in place.
Modbus Communication
– The Modbus communication example is in
Appendix 11: Modbus Poll
Example . Make sure that the correct holding register is being selected. Confirm correct register
grouping is configured by referring to the selected Data Pro Word-Order and Modbus-Mapping. Confirm
matching baud rate and the slave ID for the respective Modbus port.
