When you want to use limits you should use a Integer. Or use the event 'Change value', but then this will be executed when BOOL changes from 0 to 1 and again when changes from 1 to 0. Best regards, Wizard

Jeebs Posts: 218 Rating: (28)	Hi, I would do it differently: Create an interger tag, then use numbers in your program. Say you use MW 40 If MW 40 = 12 then open screen 12. This way would be alot easier. Create one integer tag. On the Change Value event you select OpenScreenByNumber. For screennumber you select the current tag. This way whenever the value of that tag changes, the corresponding screen will be activated. Hope this helps Jeebs
