I have worked on VFD drives, remote I/Os, Servos, Stepper motors, CPU-CPU communications, Profibus to CANbus Gateway, communication protocols (PROFIBUS, PROFINET, CANbus), technological functions (PIDs, encoders and third party sensors), and many more processes involving complex hand shake between devices.
