There isn't really a "run continuously" option, but you can have scripts run at defined intervals, such as every 2s.

See my attached document in this thread:
http://www.plctalk.net/qanda/showpost.php?p=662815&postcount=4

which shows how to realise a counter value which is incremented every second. You can add a VB script instead of a C script if you want, the settings you have to do are the same.

But if you want to do an action when a specific variable has a specific value, I would use in the trigger settings a variable trigger instead of a cyclic trigger, to keep the script load in your WinCC runtime low.
Then the script is only triggered when the value of the variable has changed. Then you read the variable value, and do some action when variable==1 or whatever you need.
