i'm working on a project in WINCC, i have severals machines connected to PLC, and i need to know for each machine the time that it was "ON,OFF, Problemes in process" etc... so i created a scripts  which can calculate  "times ON", "time OFF"...

the probleme is every machine have its own scripts and i need them to be executed simultanusly, otherwise i can't calculate the time for all of them.

so any help for me please? or if u can tell me an other way to count time would be better :)
