Function parameters - dynamic change

Function parameters - dynamic change

Hello,
I am working with Zenon 7.20 and am trying to create a faceplate for some elements (e.g. valve, pumps etc).
I have created a Valve data type:
- Status: open/close (values 1/0)
- CMD: auto-on / auto-off / manual-on / manual-off (values 1/2/3/4)
I have also created a screen which i am opening multiple times with data from different valves, by clicking the valve (using the linking rule on an invisible button on top of the valve). By changing the value for status, the text open/close changes for the corresponding valve in the opened screens.
The screen also has some buttons that have a function to "Write set value" to a tag. I need to be able to set 1, 2, 3 or 4 to CMD by pressing a button.
My question is: can i somehow change the parameter of the function dynamically so that every time i click on a valve and open a window, the function will set the value to the tag corresponding to that valve.
Example: If the faceplate for Valve_1 is opened, by clicking the button i should set Valve_1.CMD, and if the faceplate for Valve_2 is opened, by clicking the button i should set Valve_2.CMD.
Regards,
Vlad
