Hello Tumelo; SFC 39 could do positioning tasks on a CPU 314IFM with either digital or analog outputs. On the newer Compact S7-300 CPUs, such as the CPU 314C-2DP, you have 2 separate positioning FBs, one for analog outputs, one for digital outputs. You will have to compare both documents, and decide what new positioning block you want to use with your CPU 314C, based on your application parameters.

Hello Tumelo; The Search function on the forum is a very powerful tool, if you take the time to examine it. Si.plt put the closest search term you can think of, for example SFB 46, in the search box at the right of this page, and in the results page select the filters you need to limit your search. In my case, I requested only Application examples, which gave me this document: https://support.industry.siemens.com/cs/ww/en/view/48077520 Study the example to find answers to most of your positioning questions on the new CPU. And use the search functionality to find manuals, FAQs and examples for this or your next project. Hope this helps, |
