Change meter fill color from Ladder


Recommended Posts

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.
