Commands and Responses for Controller Link Units
Section 6-5
A PLC system setting errors occurs if the Controller Link Unit is not properly
recognized by a CVM1 or CV-series PLC.
A PLC model error occurs if a C200HX/HG/HE Controller Link Unit is
mounted to another type of PLC.
Count 1 to Count 8 (response): The total number of times for each of the
items listed below is returned as 1 byte of hexadecimal data.
Count 1: Number of CRC errors
Count 2: Number of token re-sends
Count 3: Number of token returns
Count 4: Number of token timeouts
Count 5: Number of polling timeouts
Count 6: Number of controller changes
Count 7: Number of active node changes
Count 8: Reserved for system use.
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.
6-5-6
NETWORK STATUS READ
Reads the operating status of the entire Controller Link Network.

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
Reserved for
system use.
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.")
