Hi,
I have to make several very precise timers to run inside my STEP 7 application. So I`m thinking in usign the #OB1_PREV_CYCLE as my base time. The definition is "Cycle time of previous OB1 scan (milliseconds)".
The question: Is this time the execution time of the OB1 execution time, or is the complete SCAN Time, including accesing to I/O, communications, etc?
Thanks in advance,
