Installing and Configuring Your ControlNet PLC-5 Backup System 3-3
Configuring With a Single Control Application
This section assumes that you have already developed your control
application and have loaded it onto a single ControlNet PLC-5
processor (i.e., a non-backup system). Throughout this section, we
will refer to this processor as the first processor. Furthermore, we
assume that you have a second processor installed, powered on, and
in its default state. Both processors must be in Program mode and
must be physically connected to your ControlNet network.
To create and configure your backup system under these
circumstances, complete the following steps:
1. Reconfigure ControlNet I/O on the first PLC-5.
2. Configure handshaking messages between both PLC-5s.
3. Configure ControlNet I/O on the second PLC-5.
4. Save the ControlNet configuration.
5. Configure the hot backup parameters on the first PLC-5and save
the project.
6. Create and download the project for the second PLC-5 and save
the project.
Reconfigure ControlNet I/O on the First PLC-5
Reconfigure all ControlNet I/O adapters and modules that will be in
your ControlNet PLC-5 backup system by changing their ControlNet
connection from Exclusive Owner (default) to Redundant Owner.
1. Launch RSNetWorx for ControlNet.
2. Check the Edits Enabled checkbox on the toolbar.
3. Right click on the first PLC-5 processor (the odd-numbered
node) and choose Scanlist Configuration.
