Hi The following snapshots may help you to do the task in WINCC7.0 . Using the internal tags is also a good choice for simulation. An internal tag "pump_on" is activated and then the values are written by using buttons.Button "ON" transfers "true" to the mentioned tag and Button "ON" make it "false". Finally a circle is used instead of a pump. Try it, it is really simple Best regards Attachmentpumps.zip (142 Downloads) |

Dear yantolet For simulating , it is OK.But , please note that you can send this bit "Pump on" to PLC and just control the actuator with that but situations is more complex in real projects.There are several conditions to be check before starting a pump such as Emergency stop push button, pump be local or manual or some process conditions.It is much better to activate stop and start signals from SCADA to PLCs and combine them with other necessary signals in PLC.
