Has anyone ever ran into this problem before?
I have a Panelview 600 on a DH-485 network with 6 MicroLogix 1500's. Each PLC is running the same type of machine so I have alot of alarm triggers and alarm messages set up in PV. About 100 alarms. The problem is this. I can go online with any of the PLC's and flip a bit to trigger an alarm (Lets say alarm 6).
I look at the PV and alarm 5 pops up. I have checked my bit numbers in PLC, alarm triggers(bits), and alarm messages... over and over ... They absolutely match up correctly. Is there anything else that could be wrong. Some of the first few alarms match up ; 1,2,3,4.. but the rest are offset by 1. My PV program is right on the edge of being to large, I had to cut it to fit in the 600. I have about decided that it is an internal PV error or something.
Thanks..
