Hi,

I'm struggling to animate a pump in Perspective environment, via Props \> state \>running, stop, etc.., while I can do that in Vision, I cannot do it in Perspective, I'm using few Boolean values from Plc to show the pump is running, stopping, fault, etc.

please can anyone help, I just recently started using Ignition.

Thanks to all!

You need to create a binding on the pump's `props.state` property. There's a dropdown there that shows you the valid options are _default, running, stopped, faulted_.

You could use an expression binding to combine the boolean flags using **binEnc** :  
[https://docs.inductiveautomation.com/display/DOC80/binEnc](https://docs.inductiveautomation.com/display/DOC80/binEnc)

and then use **case** to return one of the options above.
