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.

tions cycle time is returned in units of 100

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.

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.
