BMENOP0300 module doesn't support IO Scanning feature however the BMENOP0300 module supports explicit messaging through the Modbus TCP protocol.

Use the DATA_EXCH function block or WRITE_VAR and READ_VAR function blocks in application logic to create a Modbus TCP explicit message.

NOTE: A single Unity Pro application can contain more than 16 explicit messaging blocks, but only 16 explicit messaging blocks can be active at the same time.
