FB editor questions - MATTWAVE - 21.10.2026
I am using an LM5 for the first time as part of a KNX system to handle to basic logic. I have a good understanding of logic and lots of experience with other systems/devices but I am having issues with FB editor on the LM5.
I want to do something very simple that looks at a % demand value, and if this is greater than '0', it will output a binary 'true'. I would then like to use this 'true' to trigger a value transmitter that will transmit a value of 100%. This will be used to fully open a valve on a fan coil unit, when there is a cooling demand greater than '0'.
I am able to make the first part work, but cannot find a way to trigger a value to be sent to a KNX group address.
Can anyone assist?
