Guys,
I am after a bit of confirmation as to what a bit of logic does.
I am in the middle of making some changes to the logic on one of our cranes, the logic is all annotated in German, which doesn't help me as I don't speak a word of German, to make matters worse the FB I am looking at has no annotation what so ever!!
Here's the code:-
I think that the first seven lines (up to and including S F63.1) is a negative edge detection one shot of I0.6, the rest of the logic will turn output 1.2 (Q1.2) on for 0.5 seconds as governed by T130 when F60.0 is true (I0.6 has gone off)
I do not have access to a PLC available to try this on at the moment, not even an S7. If someone would be so kind and confirm that what I think it does is right I would be grateful.

:AN I 0.6
:A F63.1
:= F63.0
:A F63.0
:R F63.1
:A I 0.6
:S F63.1
:A F63.0
:S Q 1.2
:A Q 1.2
:L KT005.1
:SD T130
:A T130
:R Q 1.2
