Hi all,

I need to sacale a analog variable in Step 7 microwin, I downloaded scale library and I'm using S_ITR block. And now I have a problems:

When I simulate the block don't work. I just do it like siemens example. I think that the problem is in my simulate, it's possible? Which Simulator you use?

Hello,

what problems and what value you have on AIW0? There isn't oficial simulator of S7-200, so make it all on real HW. Did you check this topic, maybe it can be helpful to you:

scaling and unscaling block in step7 micro/Win

Duris, 

My problem is about the output, I can't see it working. But now, that I know S7-200 have not oficial simulator I think that's is the problem.

And I already look at this post, I do like it.

Thanks for you help 

Hello,

I know that you had problem with output, I was only ask because due your AI input value you can easy recognize problem also. You set probably range from 4mA to 20mA, but if you have 0mA signal, you can't have nothing on output, therefore I've asked about your AIW0 input value. Ok, no proble, good luck.
