Changing values with cursor key

Hi,

I want to know if it's possible to change some values like offsets or constants with the cursor key in logo.

I have a temperature sensor and a desire temperature so when the temperature is higher than the desire temperature the a fan starts working. The problem is that i want to change the desire temperature with the cursor key but I don't know how to do it.

Thank you in advance

There are 2 ways to change the setpoint value using the cursor keys.

1.) option:
By example, with a aritmetischen function. They bind the parameters V1 in a message text as an input field. Then you can change the value directly from the display using the cursor keys in the parameterization.

2.) option:
Use the cursor keys to affect the count of up / down Counter.

There are both Options in attachment.
