•
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 ProtoNode ( 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 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 persists, a Diagnostic Capture needs to be taken and sent to support.
