FX-PCX37 Expansion Input/Output Module Installation
Instructions
FX-PCX3711-0
Application
The FX-PCX37 controller is a part of the Facility Explorer
FX-PC Series Programmable Controller family. FX-PCX
controllers expand the number of points connected to an
FX-PCA, FX-PCG, or FX-PCV programmable controller
or to a supervisory controller.
FX-PCX controllers operate on an RS-485 BACnet®
Master-Slave/Token-Passing (MS/TP) Bus as BACnet
Application Specific Controllers (B-ASCs) and integrate
into Johnson Controls® and third-party BACnet systems.
Note: At FX-PCT Release 10.1, a new capability was
introduced allowing FX-PCVs, FX-PCGs, and
FX-PCAs to communicate by using either the
BACnet or the N2 field bus networking protocol.
The operation of the FX-PCX Input/Output Module
is not affected by the selection of the BACnet or
the N2 protocol in the host controller.
