Programming a Siemens S7 in C or C++

Hi, is there any way I can program a Siemens S7 313C PLC using C/C++ (or similar programming languages)?

Hello dfdgdsd;

If you have Step 7 Pro, you will have access to S7-SCL which is based on Pascal.

Of course, since this is for a PLC, you will have no dynamic memory allocation and other such features.

If you would like to have a first look at SCL, here are a few examples from this forum.

If you want more examples, do a search for SCL on this site, or on Siemens’ website for manuals and FAQs.

Hope this helps,
