Hello,
So I have a 1769-L16ER AB controller (firmware 32) connected to a PanelView Plus 7 Standard (firmware 12). When I change to a screen with an AlarmList object it gives me an error: The parameter is incorrect (see picture). After the error shows up the HMI freezes and I have to power cycle it. It took me a while but I finally found that the cause of the error AlarmList trying to display alarms that are active and unacknowledged. The error doesn't occur with other alarms (at least not that I am aware of).
Does anybody know the cause of this? If you need any more information from me just let me know.
