Thanks alot sir dp, I tried the same but there is an error in the network, can you please help me to solve this.

Do you know how to create tags?

2018.05.04 - The original version of the previous post had a picture showing an undeclared boolean tag named "edge1".

The objectives of the project mentioned in the topic:

• Control pressure with four (4) available pumps.
  
  
• The runtime of each pump is monitored.
  
  
• The next pump started should be the one with the lowest runtime.
  
  
• This is a good experience for a junior on how to design a control system for an S7-1200.
  

Hello rick,

did you define <edge1> as boolean tag?

Actually what about some Programming Training?

@dP: Could watch the gif night and day

Hi rick,

Please read the whole thread again. There is already a solution regarding your question. If you don't good in englisch, than translate all Posts in your language via googletranslator or something like that.

If the solutions don't help you than please make clear whats your problem or try it out by yourself. That's the best way to learn something. I can also recommend to see some YouTube tutorials or read some manuals to learn something. 

I think the users don't answer you, because they finally post the solution in here. Now they seemed to get annoyed by you.


Best regards,

Noodles
