Appendix A.3. Checking Wiring and Settings

No COMS on Modbus RTU side. If Tx/Rx are not flashing rapidly then there is a COM issue on
the Modbus side. To fix this problem, check the following:
o
Visual observations of LEDs on ProtoNode ( Appendix A.4 )
o
Check baud rate, parity, data bits, stop bits
o
Check Modbus device address
o
Verify wiring
o
Verify Modbus device is connected to the same subnet as the ProtoNode
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 ProtoNode ( 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 still exists, a Diagnostic Capture needs to be taken and sent to technical
support. ( Appendix A.5 )
