Network Instructions Section 3-25
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 (A21300 to 07: Communications port No.
0 to 7) will turn ON and the Network Communications Error Flag (A21900 to
07: Communications port No. 0 to 7) will remain OFF.
After completion, the Network Communications Response Code (A203 to
A210: Communications port No. 0 to 7) will contain the explicit message error
code.
