Do I need a 300 DP series with IM 151 7 and ET200S or is this doable with a 1200 series? If possible please could you tell me the full hardware list. For example, I get some solutions with All S7 1200s has 4 pulse train outputs for your stepper motors. I believe the onboard analog inputs can only do voltage measurements, so you will need an SM1231 https://eltra-trade.com/catalog/siemens-motors.
