Omron CVM1-CLK21, CS1W-RPT01, CJ1W-CLK21-V1 Network Status Read, Corresponding to the node address

Commands and Responses for Controller Link Units Section 6-5

Network participation status (response): The following diagram shows the bits corresponding to node addresses in the Controller Link Network. When a bit is returned as “1,” it means that the corresponding node is participating in the network.

Bit	7	6	5	4	3	2	1	0
Byte 1	8	7	6	5	4	3	2	1
Byte 2	16	15	14	13	12	11	10	9
Byte 3	24	23	22	21	20	19	18	17
Byte 4	32	31	30	29	28	27	26	25
Byte 5	40	39	38	37	36	35	34	33
Byte 6	48	47	46	45	44	43	42	41
Byte 7	56	55	54	53	52	51	50	49
Byte 8	–	–	62	61	60	59	58	57

Reserved for system use.

The numbers in the boxes indicate the node addresses. The bit status of a particular node address shows whether or not that node participates in the network.

0:Not part of network

1:Part of network

(All boxes marked by "–" are reserved for system use and fixed at "0.")

When CS1W-CLK21-V1 and CJ1W-CLK21-V1 Units are used and the Wired Network 62 Node Enable Bit in the DM Parameter Area software switches is ON, the network participation status of nodes 33 to 62 is returned in bytes 5 through 8. In other models, bytes 5 through 8 are reserved for system use.

6-5-6 NETWORK STATUS READ

Reads the operating status of the entire Controller Link Network.

Parameters	Participation data (response): This parameter indicates the active status of
	individual nodes with respect to the network (i.e. their participation in the net-
	work). As shown in the following diagram, that status is expressed in four bits
	corresponding to the node address.

Bit	7	6	5	4	3		2	1	0
Byte 1		Node #1				Reserved
Byte 2		Node #3				Node #2
Byte 3		Node #5				Node #4
Byte 17		Node #33					Node #32
Byte 18

Participation Status of Individual Nodes

0
0: Not part of network
1: Part of network
0: Normal disconnection	(Applicable only for
1: Abnormal disconnection	inactive nodes.)

0:Normal node

1:Non-responding node

(No response to polling)
