Hi,
Never thought this day would come, but it seems the S7-200 has something the S7-400 is lacking. Or it might just be me missing it.
My problem:
Got Valve. Valve needs to be open for 5 mins total.
When safety-door opens Valve closes due to safety issues.
Need timer to 'pauze' when door is opened.
In S7-200 this would be easy. Just use retentive on-delay timer.
In S7-400 I can't seem to find a fast and easy way to do this.
Am I missing something or is this functionality not natively supported in S7-300/400?
