Tip
If there are several tags that needs to be combined into one tag, a sample script like below can be of use:
var S1 = getTag ( 'SIM1_Lek'); var S2 = getTag ( 'SIM1_Breuk'); var S3 = getTag ( 'SIM1_Service'); var S4 = getTag ( 'SIM1_Loopim'); //turning on anyone of the tag will trigger the event. setTag( 'SIM1_Alarm', S1 | S2 | S3 | S4);
