I'm working on a PV550 connected to a SLC 5/03. Here's what happening... The machine went into alarm last night and the machine stopped. The alarm banner said that there was stepper drive fault. We checked the drive and it turned out to be fine. Seems like the proper alarm screen is not always coming up. Here's my question. How do I figure out what address has activated what alarm text in the alarm banner. In the "alarm triggers" the trigger tag is defined as N7:0 (tag name "Alarm"). The trigger type is LSBit.In "Alarm messages" there are 151 messages defined. The value/bit goes from 0 to 150. The first entry 0 doesn't have a message text entered. The trigger is the same tag name "Alarm". The alarm on the PV550 alarm banner is the last alarm message text that refers to value/bit 150 or entry 151. In the text editor window the text ID that refers to it is 982 entry number 656. The program was written in Italy and the original program with comments (probably in Italian) is lost. If I could just know what address is making that message pop-up I think I could figure out where the problem comes from. I read some posts about alarms banners, but I still can't get it.
