MSA FieldServer ProtoNode FPC-N34 - Checking Wiring and Settings

10.3 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:
◦ Visual observations of LEDs on ProtoNode. (Section 10.5 LED Functions)
◦ Check baud rate, parity, data bits, stop bits
◦ Check Modbus device address
◦ Verify wiring
◦ Verify all the Modbus RTU devices were discovered in Web Configurator. (Section 8 Configure the
FieldServer)
• No COMS on Modbus TCP/IP side. To fix, check the following:
◦ Visual observations of LEDs on ProtoNode (Section 10.5 LED Functions)
◦ Check device address
◦ Verify wiring
◦ Verify all the Modbus TCP/IP devices were discovered in Web Configurator (Section 8 Configure the
FieldServer)
• Field COM problems:
◦ If Ethernet protocols are used, observe Ethernet LEDs on the ProtoNode (Section 10.5 LED Functions)
◦ Visual dipswitch settings (using correct baud rate and device instance)
◦ Verify IP Address setting
◦ Verify wiring
NOTE:If the problem persists, a Diagnostic Capture needs to be taken and sent to support. (Section 10.4
Taking a FieldServer Diagnostic Capture)
