Commands and Responses for the Support Board
Section 6-3
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.
6-3-6
NETWORK STATUS READ
Reads the operating status of the entire Controller Link Network.
Command Block
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.
Actual communications cycle time (response):
The actual communica-
tions cycle time is returned in units of 100
μ
s 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.
