Modbus exception response

Remarks

Signals that a Modbus exception response was received. Exception responses are sent by a slave device instead of a normal response message if it received the query message correctly but cannot handle the query. This error usually occurs if a master queried an invalid or non-existing data ess or if the master used a Modbus function, which is not supported by the slave device.
