Immelmann Posts: 13 Rating: (0)	Hello from a newbie! How do i add a CONT_C block to my project? I know that i can copy the block from another project into my new one but i want to know how it is done from scratch. I can look it up under the stdlibs but not use it from there. Best regards

See this page from the S7-300 Instruction list: http://support.automation.siemens.com/WW/view/en/13206730 It displays the various CPUs that can use SFB 41, and the 312 is not in the list... You will need to go to a higher CPU, even a CPU 313C will run SFB 41. Hope this helps, Daniel Chartier Attachment CPU312_SFB41.JPG (314 Downloads)
