Commands and Responses for Controller Link Units Section 6-5

ON, the network participation status of nodes 33 to 62 is returned in the upper four bits of bytes 17 through to the lower four bits of byte 32. In other models, the areas corresponding to nodes 33 to 62 are reserved for system use.

Actual communications cycle time (response): The actual communica- tions cycle time is returned in units of 100 ∝s in hexadecimal.

Polling node address: The current polling node address is returned in hexa- decimal.

Data link operation (response): Indicates the status of data link operation in the network.

Data link operational status

0: Inactive

1: Active

Data link type (response): Indicates the data transmission status of the local node’s data links. It is configured as shown in the following diagram. This parameter is valid only during data link operation. While data link operation is inactive, the value from the previous operation is retained.

Bit 7 6 5 4 3 2 1 0

0 0 0 0 0 0 0

Local node data transmission status

0: Transmission

1: No transmission

Data link recurring error status (response): Indicates whether an error con- tinues to occur at a node when data link data is received. If an error continues to occur at the same node when the data is received, the bit corresponding to that node turns to “1” (i.e., turns ON). The configuration is shown in the follow- ing diagram.

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 there is a recurring data link error at that node.

0:No recurring error

1:Recurring error

When CS1W-CLK21-V1 and CJ1W-CLK21-V1 Units are used and the Wired Network 62 Node Enable Bit of the DM Parameter Area software switch is ON, the continuous data link error 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.
