Can you tell me, on a 6200Y Multiplex with Fusion control, what parameter Y0090, bit 8 is for? It keeps giving us a black alarm #377. It doesn't affect operation, but when it occurs, randomly on startup, it keeps repeating and wiping out the alarm history.

Steve,
It sounds like output Y0098 is giving this alarm #377. I don't think there is a Y parameter. I haven't got an access to Ladder Diagram to search for that address. What does this alarm say, is there an explanation following alarm number? Can you email me PLC ladder from this machine?
