7.7.7 1:N Communication (Computer Link (Ethernet))
Overview
A computer is connected respective PLCs through Ethernet. The computer and the PLC communicate
via commands and responses: The computer sends a command specifying the destination IP address,
and the PLC with that IP address sends a response back to the computer.
It is no problem if the unit number of the PLC overlaps with other PLCs.
1:N Communication setting (Computer link (Ethernet))
The settings for the FP-X system register and communication cassette AFPX-COM5 are the same as the
settings for the connection (computer link (Ethernet)) by a 1:1 communication.
However, set the IP address for a FP-X not to overlap with other FP-X units.
