The following SFC Chart will not cancel or pause if it is started without a parent chart. Chart XMLs do NOT copy if you include the Begin Chart element, but the rest can be copied and pasted into a chart – My poor man’s way of source control… I do something similar for the python scripts – WHAT A PAIN.

This is not a critical problem to me, since I’ve added additional checks to the chart to validate that a parent exists, which seems to have made things better. But, I thought I’d report this to you, since it brought down the whole Ignition server! I couldn’t set or clear tags or anything. The only way to recover was to stop the Ignition server, wait 3 - 10 minutes for the java process to actually stop, then restart the server!

[code]\<?xml version="1.0" ?\>  
  
Chart Name: ZoneWatchDogLoop

This chart will monitor the status of the Zone PLC, and the  
ZoneProcessing chart.  
It will set flags indicating if the master ZoneProcessing chart is still  
running or not, which the other charts will utilize to indicate if they  
should stop or not.  
  
def onStart(chart, step):  
“”"  
This will run when the step starts, before any  
other action.

Hi Bill,

Just wanted to let you know that I received the logs you sent to support, and will be looking into this today. Hopefully we can track it down soon!

Maybe you should contact IA’s actual support site or contact them via email. This forum is not official support.

I did not write the message on 9/4/2020, those are NOT my words! (Yes I’ve changed my password!)  
Interesting thing about that message, is that the forum indicates that this is the first post for BillS. That is weird since I have posted questions and rarely suggestions on these forums quite a bit.

Any and ALL issues I had with SFC on that project were promptly and successfully resolved by IA in a timely manner back in 2015!

In fact most issues that I’ve reported to IA have been resolved quickly, their support staff are some of the best I’ve dealt with. Not all issues though, just most…

Yes Mr. Turmel I know that the forums are NOT official support and I do not treat it/them as such!  
I treat the forums as a resource to suggest resolutions to problems I may have that other people may have posted. You and others including some actual IA staff have been very helpful and supportive within the context of the forums, but I do not expect to have my questions answered in a certain time frame.

Thank you  
Bill S.

As far as I can tell this is a spammer technique I haven’t seen yet. Unrelated email address but he then used the same display name and hijacked your old question. I’ve deleted and blocked the IP… hopefully I didn’t misdiagnose this.

Thanks for your email to support and followup here @BillS.
