4.4 Internal Diagnostic Modbus Registers
There are a number of internal diagnostic registers that can be accessed via Modbus TCP/RTU that will help with analyzing and diagnosing the radio network. To access these register the Modbus Server will need to be enabled and a Modbus Server address will need to be configured (See 3.16 “Modbus I/O Transfer” for details on how this is done).
After enabling the Modbus Client you can then access the following information by reading the corresponding Modbus Address at the Server ID address.
