How to update FB in CFC editor | CFC for PCS 7 and STEP 7 | SIEMENS Forum
We want to check how to update an FB in CFC editor when its interface changed. Interface of the FB is the Input, outputs, inputs/outputs and static area.
Let’s create a simple CFC application and test the concept. FB1 is created, inserted in CFC editor and the entire project compiled. Now, we add extra inputs and outputs to make a more complex logic.
You see that it is simply possible to update the FB in a chart and the IDB will be compatible with the new changes.
