AHU controllers supported a Zone Bus for connecting M100C Series networked actuators. FX-PC controllers do not support the Zone Bus, and accordingly do not support these devices. When using an FX-PC controller to replace an AHU controller that uses an M100C zone bus actuator, you must replace the actuator with a non-networked actuator. For dampers, use the M9100/M9200 Series. For valves, use the VA7800/VA-7150 Series.

To control the new actuator, use the available analog output or configurable output interfaces on the FX-PC controller, or, if none are available, add an FX-PCX Expansion I/O Module.
