I read in technical support pages article "How through external switching can you use a 0-10V analog input on a makeshift basis also for 0-20mA?" (following link) https://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&lang=en&objid=25204813&caller=view But these example is written for S7-224 XP hardware. Can I use the same value for the resistor and the same wiring diagram also for EM231 module? Thanks for help
