Additional Information
For the CS/CJ-series CPU Units, the FINS command is issued to the network of the FINS net-
work Communications Unit that has the smallest unit number.

Unit with no local network table specified, the FINS command is issued to the FINS network of the
lowest unit number.
When the opposite unit is the CS/CJ-series CPU Unit and
0
is specified for the destination net-
work address, the communication may or may not be possible as described below.
Communication is possible when network number 0 is specified
• When only one FINS network Communications Unit is connected to the opposite CS/CJ-ser-
ies CPU Unit.
• When multiple FINS network Communications Units are connected to the opposite CS/CJ-
series CPU Units, and the FINS network Communications Unit is connected to the CS/CJ-
series CPU Unit that has the smallest unit number.
In this case, the routing table setting is not required for the NX-series CPU Unit.

• When multiple FINS network Communications Units are connected to the opposite CS/CJ-
series CPU Units, and the FINS network Communication Unit is connected to a CS/CJ-series
CPU Unit other than the unit that has the smallest unit number.
In this case, routing table setting is required for both the NX-series CPU Unit and the CS/CJ-
series CPU Unit.
