TIA Portal: what's wrong with my sequence?

[asteroidehk]

Hello Friends

I have done the attached sequence but something is not working as i need.

It has 3 steps, each step advances with a timer done or a jump step. (The complete sequence should have 24 similar steps)

In Network 1 Jump_Step is a HMI Pushbutton, if you push then jump the timer to the next step.

In Network 2 Step_1 is a HMI PushButton, it starts the sequence.

As I said, each sequence advances with the timer done, but I have a problem:

If I push the Jump_Step, then jumps until the step 3. If I add more steps surely it would jump until the last step.

I need only to advance 1 step.

How can I do that?

Thanks in advance

Hi,

if you push the Jump_Step ("Finish Step") this will set 'Step_1_Done' (Network1), then in Network2 both steps are executed in the same process cycle, so
it jumps directly to network3/step3. To Prevent this you should check that 'Step_1_Done' is not set ( in Network3 use 'Step_2_Done', and so on)
