Hello everyone,

I'm working with Simocode pro V DP to control pump and i want do it  in two ways. First by remote with profibus and second by local with buttons and i change control way by switch button. i have set up all setting in simocode and wrote Chart next I defined control way by S1 and S2 I can start and stop device by button using ON/OFF local input in chart.

When i start the pump on local mode and switch to remote mode pump still working in the same time i don’t send  any signals by DP to start or stop Simocode

What I should do or add in my chart to stop device when a control way is changing  ?

Hello,

Please check the setting of mode selector & selection of enable signals in mode selector is correctly set. 

Please refer attachment for more information.

If above setting is OK & you want to ensure independent control in modes, you need to write logic using logic functions configuring mode selector as inputs.

Hello 

Thanks for your answer. I have read your PDF and i think all settings in my Simocode are correct ,please look at my screenshots. When S1 and S2 are high it is  remote control and when S1 is high and S2 is low it is  local control. To set S1 I'm using ' fixed level 1 ' so S1 is still high. I only change S2 by 'input 2' and the input is connected to switch button.
It is correct solution ? or do u have any ideas what i do wrong ?

Hello,

Your S1 & S2 settings are correct. But what you want to achieve is - when pump runs thru local & if selection is transfered/activated from remote - your pump/motor runs without interuption." Means you do not want to run pump/motor whenever mode is changed.

So I suggest you to either add logic/truth tables in program or select hardware input conditions of S1 & S2 in such a way that whenever mode will be changed, S1 & S2 input state should be changed. So internal logic will reset motor/pump to OFF condition.

Hello,

Thanks for your answer! It was helpful and I have done own logic tables now everything works fine.
