Field Value
Type:
Int32
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 address or if the master used a Modbus function, which
is not supported by the slave device.
