Updating the process value of the IO field when the value changes in the PLC

gvatte

Hello Christoph!

It seems to be a bug. You can assign a tag to the process value with a tag as usual,.

But in your case we want to use script like this  but for some reason I cant manage to get the process value to a tag or a test text box in any way in script.

 Hi gvatte! Thanks to your answer I managed to make it work. 

I put the script in the Change of the Process value.

But I have another problem now... I need the same application but in the opposite way: I need that the IO field's process value to be updated when the value in the PLC changes. Always showing the same relationship: 

IO field's process value = PLC value * 10

Thanks a lot.

If you go to the HMI Tags Table and click Properties on the Plc Tag, you have the option Linear scaling. I think this is what you want.

 Yes! That is I was looking for. I have proved and it is working. Problem solved! Thank you so much.
