On this channel we’ve previously shown how to use multiple OCS touchscreens in applications requiring dual HMI functionality. But what about using multiple OCS controllers for increased availability? How can you design, configure and program your system to allow a secondary OCS to act as a “warm backup” if the primary OCS becomes unavailable? All with a single set of system I/O? In this session we’ll guide you step-by-step so you can add “warm backup” to your tool chest of OCS applications.
