The clock markers of a simulated CPU are heavily dependent on the performance of your computer. Best rgeards, Hristo Mihalev

Aret Posts: 2348 Rating: (259)	I think i finally understood what are you trying to achieve.This is not about MMC, but about creating datablocks dynamically - am i right? SFC82-84 are supported by PLCSim (look link below) - so you can use it just as in normal PLC. http://support.automation.siemens.com/WW/view/en/36462014
