exit sequence

[Nizzo]

I need a sequence of steps that can be exited if an error is encountered.

I tried using a flat sequence to start with however I found out it's not possible to exit a flat sequence midway.

I then found this article (https://www.ni.com/docs/en-US/bundle/labview/page/determining-when-to-use-sequence-structures.html)that explains how you can use a case structure with a while loop to create a sequence that can be exited after any step however I've not been able to get it working and I was wondering if anyone know how to fix it or a better way to do this.

Regards,

I would prefer a dtate machine over stacked sequences

Except for a few rare cases the Sequence Structures should be avoided at all costs. 

A State Machine architecture is probably the most useful architecture to learn when you are first starting out. As most of the advanced architectures are often based on a State Machine or use one inside. Even the popular Producer/Consumer and Queued Message Handler architectures use State Machines in them.  

On closer inspection it looks like you are using a State Machine. 

Are you looking for a way to abort on a user event like pressing an "Abort" button?

figured it out, just needed to use the info block of the loop as input to the case structure. However if someone has a better way of doing it please let me know. thanks

it's not a stack sequence, I think that the screenshot is too low res, sorry about that

I have a bunch of valves that need to open in sequence and I need to ensure that some valves don't open if the pressure is too high. However I got it working, I just had to connect the info box of the loop to the state machine and number each step. 

Thank you

Your posts dont make sense to me. Consider posting code in the future.
