Commands and Responses for Controller Link Units
Section 6-5
Actual communications cycle time (response): The actual communica-
tions cycle time is returned in units of 100
µ
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 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.
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.
Data link data error counter (response): The total number of data link data
reception errors occurring at all nodes (node addresses 1 to 62) is returned as
a total count from the time the power was turned on. It is expressed, in hexa-
decimal, as one byte per node. The count can range from 0 to 255 (i.e., 0 to
FF in hexadecimal).

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
Reserved for
system use.
