SOLVED PPI / MPI - What are the real differences?
@zaasmi Programmable Peripheral Interface (PPI)
PPI Stands for?
All protocols are RS485 based, so that’s why both could be done on single port, the other thing is that MPI is a derivate of DP, PPI is a simpler MPI protocol and made for Point-to-Point communication.
hope that will be helped, if you have still any questions, don’t hesitate to ask me.
