The PCXs are expansion I/O modules with integral RS-485 MS/TP communications.

Note: At Controller Configuration Tool (CCT) Release 10.1 and later, the PCGs, PCAs, and PCVs can communicate by using either the BACnet or the N2 field bus networking protocol. The operation of the PCX is not affected by the selection of the BACnet or the N2 protocol in the host controller.

PCXs can serve in one of two capacities, depending on where they are installed in the control system. When installed on the Sensor Actuator (SA) Bus of equipment controllers, the PCXs expand the I/O interfaces of the controllers. When installed on the Field Controller (FC) Bus, PCXs can be used as I/O point multiplexors to support monitoring and control from a supervisory controller. The point multiplexor can also be useful for sharing points between other PC controllers on the FC Bus using peer-to-peer connectivity.

A full range of equipment controllers combined with the PCX models can be applied to a wide variety of building applications ranging from simple fan coil or heat pump control to advanced central plant management.
