Hi everyone I hope someone would be so kind to help me with this issue, I have trouble finding the way to declare a value which I want to be my temperature set point.
So I have an S7200(CPU224XP) and a Panel Siemens Touch "tp177b pn/dp 6"cstn".
and I also have a temperature sensor from which I get the temperature value and this value is located at the VD100 variable.

So I want to create a comparator where" if VD100>"X Value(35°C eg.)"then turn off the resistance(heater)

I want this variable "X temperature value" to be modified from the panel
siemens.
Do any of you know how I can declare this value in the PLC so I can set it in wincc flexible and be modified from the panel siemens?
What operator should I use in the PLC?
Thanks in advance, best regards and good vibes. =)
