Plan Your Peer-to-Peer
Communications
If your application requires peer-to-peer DeviceNet communications,
you must:
• determine which RSLogix Guard PLUS! application signals each
controller and scanner combination needs to make available to
peer controllers, and
• determine whether the chosen signals should be made available
on standard or safety connections.
Only the following data types are supported:
The next steps are to set up your DeviceNet Network as discussed in
Chapter 3.
Commission a Peer
Scanner
1. Connect the scanner to the network following the installation
instructions in Chapter 2.
2. Commission the scanner, following the instructions in Chapter 3
to set the node address, baud rate, SNN, and password, if
desired.
The next step is to create a GuardPLC controller resource with HSP
protocol as described in Chapter 6.
