Monitoring and Troubleshooting Your
ControlNet PLC-5 Hot Backup System
Chapter Objectives This chapter describes the diagnostic capabilities of the ControlNet
PLC-5 backup system, and provides you with tips to help you in
troubleshooting difficulties with your system.
The PLC-5 ControlNet backup system generates diagnostic information
to assist you with troubleshooting problems that may arise within a
backup application. Most of the diagnostic information is stored
within the ControlNet Backup Configuration and Status file. Other
ControlNet backup diagnostic information is stored in the Major Fault
Code word of the Status File (S:12), and on the LEDs of the
1785-CHBM ControlNet backup cartridge.
You can access the ControlNet Backup Configuration and Status file
directly via ladder logic and the data monitor, or indirectly via the Hot
Backup utility within RSLogix 5. The sections in this chapter refer only
to direct access to the ControlNet Backup Configuration and Status
file, though we recommend performing the same operation via the
Hot Backup utility whenever possible.
