Hello Attached you find a demo project, with following features: You can set the local variable iState (range 1-3) to simulate 1=ok 2=replace 3=damaged Image changer to display colors (1=green 2=orange 3=damaged) Online alarm list (displaying alarms for values 2 and 3) History alarm list Maybe your problem was, that you do not set the option "Log Alarm History" for all alarms. Regards Stefan
