When I try to download the FC where I call that SFC, an error occured.Is it because the CP315-2 DP isn't able to use it?

Nemo Posts: 3149 Rating: (171)	Hi Jule, which SFC did you try to download - SFC0?? http://support.automation.siemens.com/WW/view/de/1214574/0/en Is SFC0/48 already in your block-container in your STEP7-project? Normally these SFC should work for your CPU... Nemo
