Abstract
A virtual controller is configured to send control commands to an edge controller such as in I/O module that is connected to a building management system component. The IO module is configured to communicate with the virtual controller and to provide local control commands to the building management system component that are based upon the control commands from the virtual controller when communication with the virtual controller is determined by the IO module to be functioning normally and are based upon one or more fail-safe commands generated by the IO module when communication with the virtual controller is determined by the IO module to not be functioning normally.
