PCX expansion modules expand the number of input/output points connected to either a FX-PCA, FX-PCG, or FX-PCV programmable controller or to an FX Supervisory Controller .
FX-PCX expansion modules operate on an RS-485 BACnet® MS/TP bus and integrate into the web-based FX system.
Note:
With Release 10.1 and later of the Controller
Configuration Tool (CCT),
PCAs, PCGs, or PCVs
can be configured to communicate by using either the BACnet MS/TP or the N2
field bus networking protocol. The operation of the
PCX is
not affected by the selection of the BACnet MS/TP or the N2 protocol in the host
controller, when the
PCX is connected to the host controller using
the SA bus.
