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 active (i.e., par-
ticipating) in the network.

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.

All data from the upper 4 bits of byte 16 (node address 33)
though byte 32 are reserved for Wired Units (always 0).
Actual communications cycle time (response): The actual communica-
tions cycle time is returned in units of 100 μs in hexadecimal.
The numbers in the boxes indicate the node
addresses. The bit status of a particular
node address shows whether or not that
node is participating 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.")
Bytes 5 to 8 are all reserved for Wired Networks set for
a maximum of 32 nodes.
