"If you now want to change a parameter, you need to select the appropriate message text.
When the message text is selected, press the ESC key for longer than 2s. Then, a black bar appears in an input / output field.
With cursor up / down you can choose between several fields.
If you select the field to change, press the OK button (at TDE > Enter).
The black bar turns now in a blinking box. With cursor up / down, you can now change the value at this position, with cursor left / right to switch the position.
When you are finished with the changes, press again the OK button and you will return to the black bar.
Now you can select with the cursor up / down to another field, or press ESC to quit the operation."

So can  I only change the first parameter with F3 + and F4 -? The < arrow doesnt move when I click cursor key down, It stays on the top row. Maybe there is something wrong with my program I dont know.

It is not really a big deal, I can do it the way you showed me. But the cursor key down and up and F3 +, F4 - would have been easier.

 

 

It works when i simulate it.

But it doesnt work on the logo TDE (or the logo display)

It works from the web interface aswell. ( can move < arrow key up and down)

Is this a hardware or software problem?

Logo=FS01

FW version on the TDE = V1.08.01

Oh okay you were right.

You have to press ESC and then cursor key down at the same time, then the < arrow moves down.

Now everything is working! Thank you for helping me.
