on a controllogix 5k 5571, I got red light at the OK indicator. I'm not sure whether it was solid or blinking. Anyway, being a newbie, maintenance guy, I just got online and cleared it without checking the controll property menu's fault tab.
In the RSlogix5k help file, I got the following
"To clear a major fault from the controller keyswitch:
1. Move the keyswitch from the RUN or REM position to the PROG position.
2. Move the keyswitch from the PROG to the REM position.
3. To restart the program, move the keyswitch from the REM to the RUN position.
The OK LED on the controller should change from blinking red to solid green, and the RUN LED on the controller should be solid green.
4. To not restart the program, move the keyswitch from the REM to the PROG position.
The OK LED on the controller should change from blinking red to solid green, and the RUN LED on the controller should not be illuminated.
Note: This clears the major faults but not the major fault log (displayed on the Major Faults tab)."
So, based on that, next time, I will use the REM->PROG->REM->RUN method, to start the process, then turn it back to REM.
Question #1) Now, did I just lose the fault log? I know the help file says "this clears the major faults but not the major fault log." But, does it only applies to the #4 method (REM->PROG->REM->PROG), or does it also applies to #3 method (REM->PROG->REM->RUN)?
Question #2) does the same underlined statement also apply to the minor fault log as well? In other words, would I retain the info under the minor fault tab when I use either the #3 or #4 method?
