Chapter 17 Configure Peer-to-Peer Communication
Design the Logic Create Peer-to-peer Signals
Signals are transferred among controllers over the peer-to-peer
network. Consider the following when creating signals:
•
You can create as many signals as you need in the logic for all
controllers.
•
You can add signals anytime.
•
Signals with the same name can be used on more than one
controller without influencing each other (LOCAL variable), as
long as they are not exchanged via network.
•
Signals that are intended for network exchange, must have the
same name on the participating controllers. Whether a signal is
written to or read from the network is defined in the
Peer-to-Peer Editor as explained in
Configure Peer-to-peer
Communication on page 184 .
IMPORTANT
You must choose identical profiles for token groups that you
want to interconnect. If Link Mode (External) does not match,
communication between token groups is impossible.
