The introduction of SynqNet Phase II has necessitated changes to motor I/O and capture interfaces in the MPI library. Since the number of available motor I/O pinouts vary from node to node, different structures must be used to enumerate I/O signal access through the MPI. Some of the changes necessary to switch from old versions of the MPI (Analog and SynqNet Phase I) to SynqNet Phase II MPI are listed below.
