Response codes are 2-byte codes which indicate the results of command execution. They are returned
in the response following the command code.
The first byte of a response code is the MRES (main response code), which categorizes the results of
command execution. The second byte is the SRES (sub-response code) which specifies the results.
Additional Information
Certain bits (6, 7 or 15) of the response code will be ON.
When bit 6 or 7 turns ON, it indicates that an error has occurred in the destination CPU Unit.
Refer the the CPU Unit manual to remove the error.
When bit 15 turns ON, it indicates that an error has occurred during the network relay.
The following diagram describes what is a response code.
The MRES codes are shown in the following table along with the results they indicate.
Refer to the SYSMAC CS/CJ/CP/NSJ- s erie s Communication s Command s Reference Manual (Cat. No.
W 3 42) or the operation manuals for the relevant unit for further information on response codes.
