FINS Commands and Responses

Section 6-2

Refer to SYSMAC CS/CJ Series Communication Commands Reference Man- ual (W342) for details on FINS commands.

6-2-2 Sending/Receiving FINS Command/Responses

FINS commands are sent using the CMND(490) instruction for CS/CJ-series PCs. Send/receive FINS commands and responses and the data formats used are illustrated in the following diagram. Unless otherwise specified, all data is hexadecimal.

Command Codes	Command codes are represented by a 2-byte hexadecimal code. FINS com-
	mands always begin with a 2-byte command code and any parameters that
	are required follow the command code.
Response Codes	Response codes are represented by a 2-byte hexadecimal code that indicates
	the results of command execution. The first byte provides the main response
	code (MRES), which classifies the results, and the second byte provides the
	sub-response code (SRES), which provides details on the results.
