very helpfull. thanks sir

Sir for simatic manager how to do the incremental encoder homing program And how to reset the encoder value please help me

I do not understand why all of this is so overcomplicated. They create a lot of unnecessary issues at first and trying to solve them later. Automation went to the wrong way because of Siemens, Mitsubishi etc. I wish to see a new player on the market who will be more focused about smart not overcomplicated solutions instead of marketing mumble.
