Hello Zlatko; In the following popular thread on the forum, Denilson Pegaia offers an excellent explanation of FBs and FCs as different types of subroutines that are used in a Step 7 program: If you only need the routine to execute once and return a result (for example a math instruction), use an FC. If your routine parameters must be available even when it is not being executed, use an FB (+ IDB, instance DB as dedicated memory block for that routine). Examples can be easily followed in this manual: Working with Step 7 https://support.industry.siemens.com/cs/us/en/view/45531551 Hope this helps, |
