 I want to connect to the 0-10V AI on the base module in a 2 wire loop

how to connect input analog sensor (4-20mA) and logo

Depends on where you want to connect the sensor:

- To a module with 0-10V analog input (not every base module has).
- Or an analog expansion module AM2.

Please let us know which of the two options you want to use.

You may use a converter 4-20ma to 0-10V. Not expensive and you can fine tune zero and span to suit the Logo input.

Works just as well with a 500 ohm resistor.

Tolerances can be compensated for with an analog amplifier.

 Loosing 20% of the possible resolution and missing codes in the result are not my definition of "just as well".

Maybe it's good enough for the person asking the question.

So:

With a native 4-20mA to 0-10V converter you get 1000 different values as output.

With a 500Ohm resistor (a solution that I use myself and can say that it works) but you have to keep in mind that:

1. Zero of your sensor is at 2V (200 digits)
   
2. Max-Value of your sensor is at 10V (1000 digits)
