3-2-4 Checking Routing Tables for Errors
Crossing Network Layers with Version 2.0 and Later CS/CJ-series Units
With Version 2.0 and later CS/CJ-series Units, FINS commands can cross over up to
8 network layers (see note), including the local network.
Applicable Networks:
Not all networks can be crossed up to 8 times. Only the following two kinds of
networks can be crossed up to 8 times. (The networks can be crossed in any
combination.)
Controller Link
Ethernet
Note: Operation through DeviceNet networks may not be dependable.
Configuration of Compatible Models:
Both the node sending the FINS command and the target node must be Version 2.0 or
later CS/CJ-series Units. Intermediate nodes may be PLC models other than Version
2.0 or later CS/CJ-series Units, i.e., PLC models that support a maximum of 3 network
layer crossings.
Serial
connection
This does not count as a layer crossing.
