Deleting Steps in SFC

Hello all,

We (the small company I work for) are just getting into B&R stuff, and we are only a few days in. I’m still getting used to AS, but making some progress (albeit slow)—any patience with my greenness is greatly appreciated!

We were hoping to use SFC for a lot of our programming, as we are coming from AutomationDirect’s Do-More PLC line which is strictly ladder and we find SFC to be a comfortable and nice transition from there, and also two of us have some experience with it from AB and Codesys.

So on to the topic: I’m having some difficulty trying to figure how to do things, though I’ve been figuring some out with the help file and the TM242 (SFC) document. But I have been unsuccessful thus far in trying to figure out how to delete steps in the main line (furthermore, my experience in SFC is with AB, where I don’t think there is really even a main line since you can drag and drop steps and connections).

I have no issue deleting steps that are branches, but it seems I cannot delete any steps in the main line. Wondering if this is perhaps a bug in my installation, or the software in this version… Haven’t really seen anything about Automation Studio’s SFC in the forums in general, and nothing on Google either.

Any help would be much appreciated!

Edit: seems that if I make a branched step, I can delete the original step and the branched step will take its place. So basically I’m finding myself unable to delete a step row.

You have to select the step and a transition, you would end up with two transitions connected if you don’t delete one also. Might that solve it? :slight_smile:

In detail: Click on the step, hold SHIFT and click the transition. Then you can hit DEL to remove both.

Thank you! I guess that does make sense, especially considering the way that this SFC editor works. Much appreciated!
