Hi all,

i have a cycle that behaves strange,

more or less description would be:

some last (near bottom of graph) parallel branches are reset when mainline is finished

My problem is that I dont know what is exact behaviour of reseting this states

(which states are automaticly reseted and when, is this a bug in S7graph ( to me it looks like it))

In pictures.zip there are graph parts, graph 3 is main graph overview and graph1 and 2 are parts of graph...

right states (S10 and S94) are both canceled when s9 exits, I even added timers as a condition

(s94 is only for this testing and it should not exit time is set to 1000 s) but as soon as s9 is over it is reset)

Subcycles behave just a bit diferently (capture.bmp) s31 stays on but s30 is reset as soon as s29 exits (now i dont have jumps i use main cycle to start stations and detect station endings stations just goes to off when it is done ...)

I used to program sfc / graph on other plcs (omron mitsubishi direct logic...) with all their specifics,

but I can not find the rule that would apply to situation here on siemens graph.

For now it looks like leftmost branch will triger autoreset (but i am not sure, and none of graphs i worked before would do something like that as i newer sad anything about subcycle end state (omron has something like that in subcycles, but it resets complete subcycle)

Simple question is if there is Auto reset,

what can triger autoreset.
