is valid when Error is FALSE.
BOOL TRUE / FALSE
RS232_Link_ErrorID
Outputs communication error code. See error codes and
their meanings as below:
1: Unidentified function code
2: The address in the response message from the slave
is different from the configured address.
3: The length of received data in the response message
from the slave is inconsistent with the configured
length.
4: Data-receiving timeout
5: Checksum error
6: The configured lengths of data to be read and written
are both 0.
7: The length of the data that is actually received
exceeds the max. received data length.
8: Data-sending timeout
16#80+ exception code: the exception code from the
slave
