Why do I see the error "Parameter access error in fieldbus module" when trying to modify the optionally mapped input or output parameters for I/O scanning of ModbusTCP?

This error occurs if you attempt to modify or write these optional parameters while the MbEthScanner parameter is set to ON

To solve this issue do the following.

Using SoMove Lite, Go to the parameter section for Modbus TCP and set EthMbScanner to off.
Save to eeprom and restart drive.
Next go to Ethernet I/O data and populate the optional parameters you wish to read/write.
Then go back to Modbus TCP and turn on EthMbScanner again.
Save to eeprom and restart the drive.
The optional data should now be populated.
