Tia Portal: Can't move lokal variable to Motion block.

[mulderm]

Hello,

In Tia Portal I put a motion block called MC-MoveRelative from the Technology instruction.
I choose an instance datablock and I want to move the variable to the block.
It will be red and after compiling I get an Error: the tag is read only
Using the help-function but will not help.
See also attached files.
Somebody knows the problem and a solution?
Thanks if you want to help me.

Greetings,
mulderm

The output will be written by the FB.

You don't need to move the tag outside of the FB.

Thank you for you fast reply Rob.
I want to use the output-bits/word for read out and use the bits
in my program.
So now I make tags with bits/words in the Static and use it for the outputs.
But I was thinking to use this bits from the generate motion block but no way.

I strongly recommend you look into these and use them

ie… Laxis blocks
