Communications Flags
b) When the Explicit Message Was Sent But an Explicit Error Response Was Returned
In this case, the explicit message was sent but an error existed in the explicit message command frame
(code not supported, illegal size, etc.). Here, the Explicit Communications Error Flag (A213.00 to
A213.07: Communications ports 0 to 7) will turn ON and the Communications Error Flag (A219.00 to
A219.07: Communications ports 0 to 7) will remain OFF.
After completion, the Communications Port Completion Code (A203 to A210: Communications ports 0
to 7) will contain the explicit message error code.
