I am doubting on how to wire an analog sensor to this SIEMENS Analog Input module:
https://support.industry.siemens.com/cs/attachments/109475183/et200sp_ai_8xi_2_4_wire_ba_manual_en-US_en-US.pdf
My sensor has the following terminals: "+" and "GND".
As you can see in the manual there are 2 possible terminals for the first channel: "1" and "9".
Which one should be connected to the "+" on my sensor. I think that should be the "9" but the plus sign on the terminal "1" name makes me doubt.
On the other hand, makes any difference if the sensor is loop powered or not loop powered.
Thanks!
