Communications with the Controller from outside the LAN and communica-
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.
1:1 Connection
In the following example, a measurement command is input and those results
are read.
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:
