Hello RCS-Engineer; A function (FC) in Step 7 programming is a piece of code that you will want to repeat many tiimes in your program, with different addresses (parameters) so you can control various instances of the same code. For example, you could program a motor control in your FC1, and call it for as many motors you have in your project without having to reprogram all the networks. Simply change the parameters of the FC1 every time you call it for a new motor. One document could be particularly interesting to you, since you are working with Step 7 v5.x (basing myselkf on the Conference you have selected. It is the Working with Step 7 v5.5 manual, which goes through the different blocks and programming structures you can use in a Step 7 project in a very didactid fashion. https://support.industry.siemens.com/cs/ww/en/view/45531551 It would be worth your while to spend a few minutes looking it up.It explains what a function does, how it does it, what parameters can be inserted for every instance of the function, and how to call the function rom OB1 (or another function or function block). Hope this helps, Daniel Chartier |
