FINS Commands Section 3-1
• The following table shows the maximum number of network levels that
can be crossed by various PLC models.
*1: Not possible with a CP1E CPU unit.
• When crossing up to 3 network levels, the CS/CJ-series CPU Units with
unit version 2.0 and later, CP-series CPU Units, and NSJ Controllers can
be combined with other models. When crossing 4 to 8 network levels,
configure the system with only unit version 2.0 and later CS/CJ-series
CPU Units, CP-series CPU Units, and NSJ Controllers. (Other models
cannot be combined in the network with CS/CJ-series CPU Units with unit
version 2.0 and later, CP-series CPU Units, and NSJ Controllers.) If ear-
lier models are used, a routing error (end codes 0501 to 0504) will occur
and the response may not be returned to the node that sent the com-
mand.
For details, refer to 1-4-2 Communications through a Maximum of 8 Network
Levels in the CS Series PLC Operation Manual or the CJ Series PLC Opera-
tion Manual.
Types of FINS Commands There are basically two kinds of FINS commands: Those addressed to CPU
Units and those addressed to CPU Bus Units. Among FINS commands for
CPU Units, there are commands addressed to the various models of CPU
Unit, such as the CS/CJ/CP-series CPU Units, NSJ Controllers, CV-series
CPU Units, C200HX/HG/HE CPU Units, and so on. The basic code system is
the same, but the detailed specifications vary according to the CPU Unit.
Among FINS commands for CPU Bus Units, there are commands addressed
to Controller Link Units, to DeviceNet Master Units, to Ethernet Units, and so
on.

Addressed to CS/CJ/CP-
series CPU Units and NSJ
Controllers
CS/CJ/CP-series CPU Units and NSJ Controllers can receive FINS com-
mands from a PLC (CS/CJ, CVM1/CV, or C200HX/HG/HE(-Z) CPU Unit) or
computer on another network or from a host computer connected directly to
the local network.
