I'm trying to help out someone that has the same setup as i do clear a fault light on a slc 5/03. What happens sometimes when we loose power is the fault light comes on and the program won't run...all i do is hook up a laptop thru a AB-PIC, go to processor status and "clear major errors"...light goes out and everything is fine again. Now we have the same setup 800 miles away from me that is having the same problem. I've been trying to talk them thru it but their laptop is a mess and i'm having no success getting the drivers for the PIC to work and what not so there is no going online. So the simple question is "can you clear major errors without going online with RSlogix 500?" Also for future processor faults, what whould be the best way to setup a manual push button on the panelview or whatever to clear errors? or would you just set the s:1/8 bit to 1 and reflash to eeprom?
