I'm a beginner of the CODESYS .
We are making a program to keep the rotation of the pump in accordance with the temperature change.
It will start operating the pump manually and then continusly control the current vale.
The automatic control prgram of the pump is made in the functionblock.
I want to calculate based on the value I enterd from the touch panel.
But I don't know how to overwrite the numerical value from I input manually to the value.
For some reason ,the pump must always chage to control the change in temperature.
I want to do continuous control based on the current value which I enterd manually.
However ,even if it calculate the numerical value,it will not be able to change the original input value.
It would be helpful if you could tell me the specific solution to this problem.

Thank you.
