tions between multiple personal computers and the Controller may not func-
tion properly. Also, communications cannot be performed between two
Controllers or between a Programmable Controller and the Controller.

1:N Connections
With this connection format, one personal computer can communicate with
multiple Controllers via a hub.
Make sure the IP addresses set for the Controllers are not duplicated.
Example:
IP address
192.168.250.010
Start the TELNET communications software on the personal computer for
each IP address and access each Controller.
The method for inputting commands is the same as for 1:1 connections.
