This is definitely not the right place to use the RevPi System. It is designed to be a a PLC as well as an IPC or Gateway system. This mixture makes it unique compared to standard PLCs. But any system needing cycle times in the 1 ms range or below can't be controlled by a RevPi. But try and find any PLC which is able to speak nearly every known fieldbus or can easily be used as a gateway for IoT projects.
