What scheme do you use for 4-20 mA (4w/2w)? Is 4-20 obligatory or you can change it to 0-20 for example? |

Hi, take a look at the manual of s7-300 modules (http://support.automation.siemens.com/BR/view/en/8859629 ) at the page 292 -297. It has the connection diagram for each type of use. Note the both channels are equally configured. |
