Change meter fill color from Ladder

[Cristian]

Hi all,

I have a meter control on a HMI which I want to change the fill color depending of Link value. for example set fill color to red when value is below 50 and set fill color to green when is equal or bigger. How can I do this?

 

regards

The fill color for a bar is not possible to dynamically change, but there is a way to accomplish what you need.

 

Since it is possible to layer different elements on the HMI in UniLogic you can place multiple meters placed on top of each other. Each one being a different color. You can also use the hide bit on each element to hide the meters you do not wish to see.

 

For example have the green meter showing normally. When the value is below 50, hide the green meter and then enable the red meter. Both meters will still be linked to the same tag value.

I'll add your request to the features request. I can't promise anything though.

Thanks for the help, I will use differents elements for now but I hope future versions allow interact with HMI elements

OK.

I've implemented this feature for meters and tanks, on both HMI and Web Server.

On Meters, this feature is enabled only on "Fill Solid" mode.
