Installing and Configuring Your ControlNet PLC-5 Backup System
Reconfigure ControlNet I/O on the First PLC Processor
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.
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 node) and
choose ControlNet Configuration.
The ControlNet Configuration screen appears.
4. For each entry under the Connection Type column, double click
on Exclusive Owner, choose Redundant from the pull-down
menu, and press Enter.
Configure Handshaking Messages With RSNetWorx
Within your backup system, you must use RSNetWorx to set up the
send and receive scheduled messages that allow handshaking to occur
between the two ControlNet PLC-5 processors that comprise your
backup system.
For each of the processors comprising a backup system, you must
create two scheduled peer-to-peer messages: one Send and one
Receive. These messages must be exactly five words in length. From
the ControlNet Configuration screen for the first processor, follow
these steps:
1. Right click on the even node (Node 2 in this example) and choose
Insert Receive Scheduled Message.
