structure is used for the control operation. Analog output of RIO600 can be written
only by using the write single register function.

Exception codes

Only a few exception code alternatives exist for the write coil and write register
requests in Modbus. If the write permission has not been provided for the client to
write a value to either binary or analog outputs, RIO600 does not consider the write
request but responds with an exception code for the respective operation.

System status register

SSR1
The device health status SSR1 register is located at 3X/4X address 0. The bits in SSR1
give an overview of the RIO600 health.
