Indicator to change color on value from modbus tcp

[Robin Holum]

Hi,

Can anyone show me an example on how to add an indicator to the form, and how to change its color depending on the value, either analog value from holding register or bit from a coil.

What control should i use and how should i use it?

Best regards

Use a THMIText togheter with a THMILabel

The THMIText will change de background color, the THMILabel will display the value.

You can use THMIColorPropertyConnector too.

Thank you fabio :)

I got the THMILabel working. But i am not quite sure on how to change the color of THMIText if value is equal to for example 10. Do i need to code it or only change a parameter?

[Fabio Luis Girardi]

Only change parameters.

[Robin Holum]

Im sorry for asking dumb this dumb question but which parameters do i need to change to get the background color to change if value = 10?

[Fabio Luis Girardi]

On THMIText you will have a property called Zones. It's a collection of TTextZone. Each zone has a condtion that will say if it will displayed or not. You can have a defatult zone when no other zone has been selected to the current tag value.

You can insert how many text zones as you want.

Thank you Fabio!!! Exactly what i was looking for

Just need to know where and what the parameters are doing.
It can probably be found in the class?

Lets say i would like to tie a tag up to a TDTAnalogueGauge, how can i acheive that?

Also, i am very interested in creating a alarming function. Any input on this is highly appreciated.

Best regards
