Mishal11 Posts: 69 Rating: (0)	Hi I need some help with programing a s7-200 to control 2 pumps What i am trying to do is, to program the S7-200 with LAD to run 2 pumpsso that Pump 1 runs for 5 min while pump 2is off and after 5 min pump 1 turns off and pump 2 goes on and after another 5 min pump 2 goes off and pump 1 goes on, So that every 5 min one goes on and one goes off I am able to do this with the LOGO! using the Asynchronous pulse generator. Is there a Asynchronous pulse generator in the S7-200 ??
