FB41

Hello,

maybe invert output bit/memory (control valve) is enough for you as solution.

Hi,

you can reverse the direction of control action of a controller by entering a negative value for the gain at the "GAIN" input of the controller.

please check the following FAQ:

hi,

For Temperature control better use the FB58 TCONT_CP.

It is for controling of temperature processes.

When your valve opens it cools down, rigth?

For controlling a cooling-process, you need to parametrize the GAIN with a negative value.

Also have a look to the extensive help of the block.

hope this helps,

regards,
