The PCA3613 controllers can communicate using BACnet MS/TP, N2, or wireless Zigbee. By default, the FX-PC family controllers and network sensors communicate using the standard BACnet® protocol, based on the ANSI/ASHRAE 135-2004. FX-PCG, FX-PCX, and FX-PCV controllers are BTL tested and listed as BACnet Application Specific Controllers (B-ASCs). FX-PCA field controllers are BTL-listed as BACnet Advanced Application Controllers (B-AACs). The NS Series Sensors are BTL-listed as BACnet Smart Sensors (B-SSs). The BACnet protocol is a standard for ANSI, ASHRAE, and the International Standards Organization (ISO) for building controls. Release 10.1 of the Controller Configuration Tool (CCT) 13.0 can be used to switch the Field Bus communications protocol in FX-PC Controllers to be either the standard BACnet MS/TP or the N2 protocol. BACnet MS/TP is the default communications protocol for all new controllers. Switchable communications protocols provide a cost-effective upgrade and modernization path for customers with existing N2 controllers. The Modernization Guide for Legacy N2 Controllers (LIT-12012045) and the controller-specific documentation provide installation and commissioning support and include tips for efficient and safe replacement. Refer to the N2 Compatibility Options chapter of the Controller Tool Help (LIT-12011147) for information about mapping N2 Objects in controllers with switchable communications protocols. The N2-capable FX-PC controllers can be used as functional replacements for legacy N2 controllers.

The N2-capable FX-PC controllers:
  • have the I/O quantities and characteristics of the FX-PC family controllers
  • must be programmed with CCT 13.0 and later, which has programming capabilities that are similar (but not identical) to HVACPro, GX9100, GPL, and other legacy tools
  • support SA Bus devices
  • support WRZ wireless sensors from the controller using the WRZ7860 receiver when configured for BACnet MS/TP communication
The N2-capable FX-PC controllers:
  • do not support Zone Bus (for example, TMZ sensors and M100 actuators)
  • do not support pass through in the commissioning mode
  • do not support remote downloading or commissioning using BACnet routing
  • do not support wireless connection to the N2 bus
