•
No COMS on Modbus RTU side. If the Tx/Rx LEDs are not flashing rapidly then there is a COM
issue. To fix, check the following:
o
Visual observations of LEDs on COM CARD (
Appendix A.4
)
o
Check baud rate, parity, data bits, stop bits
o
Check device address
o
Verify wiring
o
Verify device is connected to the same subnet as the COM CARD
o
Verify the
Modbus device was discovered in Web Configurator (
Section
5.2
)
•
Field COM problems:
o
If Ethernet protocols are used, observe Ethernet LEDs on the COM CARD (
Appendix
A.4
)
o
Check dipswitch settings (using correct baud rate and device instance)
o
Verify IP Address setting
o
Verify wiring
NOTE: If the problem persists, a Diagnostic Capture needs to be taken and sent to sup-
port.
