Omron CJ1W-CLK21-V1, CVM1-CLK21 Response Codes, Configuration, IR, SR, LR, HR, and AR Areas

Response Codes															Section 6-7
IR, SR, LR, HR, and AR Areas:
Bit	15	14	13	12	11	10	9	8	7	6	5	4	3	2		1	0
		Bit 14		Bit 12		Bit 10		Bit 8		Bit 6		Bit 4			Bit 2			Bit 0
	Bit 15		Bit 13		Bit 11		Bit 9		Bit 7		Bit 5		Bit	3		Bit	1

The status for each bit is as follows:

OFF (0): No forced status in effect

ON (1): Forced ON or forced OFF

Timers/Counters: Status of the Completion Flag will be returned as fol- lows:

00 (Hex): No forced status in effect

01 (Hex): Forced ON or forced OFF

6-7 Response Codes

This section describes the response codes returned with responses to FINS commands. Response codes can be used to confirm normal completion of command execution or to troubleshoot problems when commands fail. For fur- ther troubleshooting information, refer to SECTION 9 Troubleshooting and Maintenance of this manual and to the operation manuals for specific Units or Systems.

6-7-1 Configuration

Response codes for FINS commands consist of two bytes that indicate the result of executing a command. The structure of the response codes is shown in the following diagram.

					First byte								Second byte
Bit	7	6		5	4	3	2	1	0	7	6	5		4	3	2	1	0
			Main response code (MRES)										Sub-response code (SRES)
			1: Relay Error Flag										1: PLC Non-fatal Error Flag
													1: PLC Fatal Error Flag

The main response code (MRES) in the first byte classifies the response and the sub-response code (SRES) in the second byte indicates details under the MRES classification.

If bit 7 of the first byte is ON, a network relay error has occurred. Refer to 6-7- 2 Network Relay Errors for details on troubleshooting the error.

If bit 6 or 7 of the second byte is ON, an error has occurred in the PLC or com- puter returning the response. Refer to the operation manual for the device returning the response for details when troubleshooting the error.
