Installing The Hardware
Follow these steps to install the required hardware for your backup
system.
1. Set the ControlNet node address numbers for each of the
PLC-5 processors.
The addresses must be consecutive, with the lower number
being odd. For example, a valid node address pair is 1 and 2.
You can set the ControlNet node address via the rotary
switches on the top of each processor.
2. Insert the ControlNet backup cartridge into the EEPROM slot
of each PLC-5 processor.
Note: If the ControlNet backup cartridge is not inserted into
the PLC-5 processor, that processor will operate as a normal,
stand-alone processor, and will not exhibit any of the
necessary backup functions.
3. Install each PLC-5 processor into a separate 1771 chassis.
4. Install a power supply for each chassis, and connect to ac
power.
