Hello paranthaman; Have a look at the following quote from this manual: Programming with Step 7 v. 5.5: Scan Cycle Time The scan cycle time is the time required by the operating system to run the cyclic program and all the program sections that interrupt the cycle (for example, executing other organization blocks) and system activities (for example, updating the process image). This time is monitored.The scan cycle time (TC) is not the same in every cycle. The scan time (or cycle time) of a CPUincludes IO processing, communications and all program blocks running times. So you cannot set the cycle or scan time of a FC or an OB in particular; you can only make it as short as possible so the overall scan time is also short. Hope this helps, Daniel Chartier |
