Additional Information
The User Defined CAN Unit supports sending and recieving functions for messages. Every mes-
sage in CAN communication has an identifier. The configurable options for these message iden-
tifiers are 29-bit or 11-bit size for each input and output message buffer. See sections below for
more information.
Response Codes
Response codes are represented by a 2-byte hexadecimal code that indicates the results of com-
mand execution. The first byte provides the main response code (MRC), which classifies the results,
and the second byte provides the sub-response code (SRC), which provides details on the results.
The main response codes are listed below. More information about response codes and sub-
response codes can be found in the following pages.
Additional Information
Refer to the
SYSMAC CS/CJ Series Communication Commands Reference Manual
(Cat. No.
W342) for further details on response codes, including sub-response codes (SRC).
