Motor I/O Enumeration Changes

With old versions of the MPI, all digital inputs were included into one enumeration, MPIMotorInput, while all digital outputs were included in another, MPIMotorOutput.

With SynqNet Phase II, digital I/O has been split up into 3 categories:

  • Dedicated Inputs - represented by MPIMotorDedicatedIn, refers to common inputs such as the home line.

  • Dedicated Outputs - represented by MPIMotorDedicatedOut, refers to common outputs such as the brake enable line.

  • Configurable and/or Node - Specific I/O, represented by MPIMotorIoMask. Presently, these only support digital inputs or outputs. In the future, support for stepper motor output and compares will be supported by these I/O.
When upgrading application code to SynqNet Phase II, check the drive manufacturer's configuration type and documentation for details about which configurable I/O are supported. If the enumerations are replaced without verifying a drive's capabilities, an application will compile, but it may not work.

The tables below shows how to upgrade motor I/O enumerations to SynqNet Phase II.
