3-2 Installing and Configuring Your ControlNet PLC-5 Backup System
6. Wire the ControlNet network to the PLC-5 processors and to the
ControlNet I/O adapters being used for the backup system.
The network cabling may consist of single or redundant
channels.
Basic installation is now complete.
7. Set the keyswitch to Program mode on each processor and
apply power to the processors.
Configuring Your Backup
System Before you begin, make sure that you have installed RSLinx, RSLogix5,
and RSNetWorx for ControlNet software. For assistance with installing
any of these packages, refer to their respective installation
documentation.
There are two basic configuration paths. Select the appropriate path
based upon the type of backup system you are creating.
• If you are creating a backup system with identical (or nearly
identical) control applications in the primary and secondary
controllers, complete the steps in the section of this chapter
entitled “Configuring With a Single Control Application.”
• If you are creating a backup system where the secondary
controller is running a different application than the primary,
complete the steps in the section of this chapter entitled
“Configuring With Different Applications.”
IMPORTANT
Make certain that both ControlNet Hot Backup
PLC-5s and the Hot Backup I/O are on the same
ControlNet network. Bridging to another ControlNet
network is not allowed.
IMPORTANT
In non-redundant media applications, place your two
PLC-5 processors as the 2 nodes closest to a
terminator on a ControlNet segment. This eliminates
the possibility for a malfunctioning cable between
the processors to allow each processor to control a
subset of the I/O.
