FINS/TCP Method
Section 8-3
• When routing tables are used for one or more other nodes on the same
network
It is not necessary to set routing tables if one Communications Unit is
mounted to the PLC and the nodes are connected as one network.
(2) If EtherNet/IP is selected for CX-Programmer communications, FINS
message communications and remote programming/monitoring from the
CX-Programmer will be possible as long as CIP routing is possible for the
entire communications path. Routing tables do not need to be set. If FINS
messages are sent from a PLC, however, then routing tables must be set.
