Check Wiring and Settings
• No COMS on Modbus RTU side. If the Tx/Rx LEDs are not flashing rapidly then there is a COM
issue. To fix this, check the following:
o Visual observations of LEDs on the ProtoNode (Appendix A.4)
o Check baud rate, parity, data bits, stop bits
o Check device address
o Verify wiring
o Verify the Modbus device(s) were listed in the Web Configurator (Section 5.3)
• 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 persists, a Diagnostic Capture needs to be taken and sent to support.
