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.
When CS1W-CLK21-V1, CS1W-CLK23, CJ1W-CLK21-V1, and CJ1W-CLK23
Units are used and the Wired Network 62 Node Enable Bit in the DM Parame-
ter 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.

Response Block
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
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.")
