Event Structure & Add Stop priority during a process

[Minikisscool]

Hi all,

In my program, I use an event structure and during a process, I want to add Stop Emergency button.

How can I do ?

Thanks

What exactly should this emergency stop button do that isn't already being done by the stop button you have in there now?

[Minikisscool]

For example, if the process has 10 step, Emergency button can stop at least between 2 step

Use a state machine and don't congest event cases. They should always completed immediately.

What happens in the various "steps". Just a waits or something that takes a while and cannot be interrupted?

[Minikisscool]

something that takes a while and cannot be interrupted, so wait the end of 1 step before interrupt

[altenbach]

Again, don't use a sequence. Use a state machine and check termination after each state.

ok, I never use State Machine, I will look for an example
