10.3 Checking Wiring and Settings
No COMS on the Modbus RTU side. If the Tx/Rx LEDs are not flashing rapidly then there is a COM issue. To fix this
problem, check the following:
• Visual observations of LEDs on the ProtoNode. (Section 10.4 LED Functions)
• Check baud rate, parity, data bits, stop bits.
• Check device address.
• Verify wiring.
• Verify the device was listed in the Web Configurator (Section 9.3 Setting Active Profiles).
No COMS on the Modbus TCP/IP side. To fix this problem, check the following:
• Visual observations of LEDs on the ProtoNode. (Section 10.4 LED Functions)
• Check device address.
• Verify wiring.
• Verify the device was listed in the Web Configurator (Section 9.3 Setting Active Profiles).
Field COM problems:
• Visual observations of LEDs on the ProtoNode. (Section 10.4 LED Functions)
• Verify wiring.
• Verify IP Address setting.
NOTE:If the problem still exists, a Diagnostic Capture needs to be taken and sent to support. (Section 10.5
Taking a FieldServer Diagnostic Capture)
