If you need to verify that the remote PLC (or a computer system emulating a 2572 PLC server)
actually executed the request to store the data, you can monitor the error status. If a problem occurs
while executing the command, the 2572 will set the CMD ERR bit and place the applicable error
code in the Error Word. See Appendix D for additional information.
