what's with 1BH30 (analog output module)?

edwin saputra

In X11 on pin 4 and 5 = 16 volt, but i'm inject value to value of norm_x is 0 (min = 0 and max 10) and out of norm_x = 0 and enter to scale_x with min = 0 and max = 27648, value of scale_x = 0, but i meassured in pin 4 & 5 the voltage is 16 volts.

Greetings Edwin,       (below works from Hugo's info)

Do you have anything connected to pins X11.4 and X11.5?
There should at least be a resistor between these for you to be able to measure.
The device you connect see the voltage between these pins.

It will be most helpful if you show a circuit diagram.

Measure with a meter all the connected pins to one common signal ground.
This aims to catch if there is any wires not properly connected.
Especially X10.2 is important.

As additional (unrelated) notes:
* Suggestion: Do not use the force table to view signal states.

* Suggestion: Type in INT values to SCALE_X.MIN and SCALE_X.MAX... these values apply to the outgoing SCALE_X.OUT pin which is set to INT.

* How sure are you that QW96 is configured for the output.. double check all your hardware settings.

* Seeing MD1 makes me wonder.. is MB0 used somewhere?
You do know that MD1 has elements MB1, MB2, MB3, MB4 or also MW1 MW3?
That also means MW0 or MD0 will also overlap MD1.

i didn't connect it with anything. excuse me, please explain about MB, MW, MD !

i attached a new images for detail.

1) Connect a resistor. Maybe something like a 3300 ohm, 0.25W resistor.

2) Read this contribution by zzvss (thanks).. maybe it helps:

Hi edwin saputra,

Maybe help:

SIMATIC S7-1200 Easy Book

SIMATIC S7 S7-1200 Programmable controller

Technical specifications A 4 CPU 1241 (page857) and analog signal modules A 7 (page907).

Best regards.
