NAQ doesnt work? #129

Hello everyone

I have a new problem. I have a Siemens Logo. I want to read an analog output into NodeRed. I can let other inputs and outputs communicate wonderfully between Logo and NodeRed. Now it somehow fails with the correct addressing of the analog output in NodeRed.

I think I also have to use an analog network output, which in my case is NAQ1. image

When I look at the contrib-s7 page of NodeRed, I see that the address for NAQ is addressed as in the following picture.

I understand that DB1,WORD1406 is the address for the NAQ1. But somehow this does not seem to work. Is this correct so far?
