Hi, in my current program there is a whole menu with multiple screens aimed to help the user modify parameters. As you imagine, parameters are modified the usual way by holding escape, choosing the parameter, press enter, modify the parameter, then escape twice.

Considering most screens have only one parameter shown, is there a way to modify said parameter directly using escape+arrows commands?

I assume this function wasn't integrated by itself, but even if i try to do things outside of screen blocks, there's no way to know which screen is currently shown which means it's impossible to discriminate which parameter to change.

So is there a way to recover this information?

Hello Satixi,

you can find on the LOGO! homepage an application example for menu control with LOGO! TD. Instead of LOGO! TD Function keys you could also use the Cursor keys of LOGO! BM to navigate through the menu and modify values.

Select "Display" in the overview of the application examples, so you will find it more easy.

I hope it will help you!

Thanks for the examples! Unfortunately in my current program i'm almost out of blocks so i won't be able to incorporate this solution, but i'll maybe use it in smaller applications.

It's really too bad there's no simpler way to do this natively.
