Parameters
166
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.

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.
3 2 1
The numbers in the boxes indicate the node
addresses. The bit status of a particular
11 10 9
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.")
