Good evening, I have a reasonable knowledge of Plc programming which is self taught over the years and have good successful projects under my belt, however I have never used HMI's in them.

I have tried searching for some documentation which informs you how to program the function keys to the logo program. I have discovered from various searches that you cannot use the function block input on logosoft as this is for the Td panel. I have tried various options to get this to work but with no prevail.

I have set up analogue outputs which are shown successfully on the him from vm mapping the counters etc but cannot link the function keys. I would be greatful for any assistance / docs.

I am currently using V14 Tia. 12/24rc logo 8. Kp300 basic panel with 10 function keys

Thanks Again.

Mark

Good morning, I have tried to implement your example onto the HMI as a bool, once compiled everything is ok but when I test it on the device nothing happens?

I assume either it isn't a bool tag or I'm missing an important step.

Thanks again
