Knowledgebase article 495070:

What would cause a controller to log a Type 17 Code XX minor fault?

The Type 17 minor faults were added to the controller in Version 18 of RSLogix 5000.

As the controller runs, in the background, many diagnostics on the controller. The controller needs to make sure that each diagnostic completes within 8 hours. If a diagnostic does not complete within the 8 hour time limit a Type 17 minor fault will be logged. The code indicates which diagnostic failed to complete. Below are the error codes and fixes:

Type 17 Code 11
In Version 20.054, 20.055, and 20.056 this will be logged. This is a nuisance anomaly.
Fixed in V20.057
Fixed in V24.052
What version are you using?

I using version 20.055 and I use redundancy.
Before the minor fault occurred,CPU-1 be master and CPU-2 be slave,
After CPU be exchange.CPU-1 be slave and CPU-2 be master.
And than internet discontinue,SCADA lost connection to PLC.
