How to pause the main program and resume it the first sequence again?

[astroboy]

I am building the main program. How do I pause it in case of activated emergency button or errors? Once the button is deactivated and errors are corrected, I need to resume it again at the first sequence, like reset, not close the program. How to do it?

Hello astroboy,

you have to program it...
A construct like "if not(error) then continue else startover" could help. Also the error cluster and its use in (nearly) all communication VIs can help you. And it could help to connect such error cluster to a case structure...

Best regards,

In addition to what GerdW said, this would be much easier to do if you were using a state machine rather than a sequence. If you aren't familiar with state machines here are some links (the second might be particularly interesting to you).
