Hello people,

I buy an analog output for controlling the frequency of a dimmer.

I have a problem with my module « Analog Output » (6ES7 232-4HA30-0XBO) or I don’t understand how he works, I have a little experience of Siemens but I love this program when I understand the functioning all blocs. I search a tutorial or a same problem in the forum and I don’t find.

Just, I find this and not help me perfect: https://support.industry.siemens.com/tf/ww/en/posts/what-s-with-1bh30-analog-output-module/136054/?page=0&pageSize=10

I understand blocs has used and the maximum value to write (27648). But, when I measure with a voltmeter, and change the value, I all measure 0V (0-0M). I connect a resistor between 0-0M, but it doesn’t change the voltage.

The led of the output analog is green. 

Kind regards

**Sorry for my english, i tried best translate for you and understand my problem

What I see on picture, you putting 4 to QW8 ( 4 = 0.0015V ), just put 27648 to QW8 and meassure if get 10V.

Also check hw configuration, if your output module is using 0..10V output (you can choose between voltage/current output).

Thank you :) You are the boss.

If for a voltage of 10V output, i write two time ( scale_x and norma_x) 27468 for the maximum value, why some people on Youtube write one maximul is 27468 and for the second maximul value is 10 or 20? 

He doesn't work if i make as Youtube....

I'm interested to understand, why some poeples write 10 or 20 for blocs

Hello,

look, simply they scale that range from 0-27648 to range 0-20 that's all. Look at that Picture, there's value 10500 from first scale, that's mean 27648/10500->2.63, so in second scale 20/2.63->7.6 so look at that second result, is it that?

Ah, thanks for the explanations. Now it's  clear for me.

Kind regards
