Setup and adjustments
Important:
Electrostatic discharge can damage controller components. Use proper
electrostatic discharge precautions during installation, setup, and servicing to avoid damaging
the controller.
Setting the device address
FX-PC Series Controllers are master devices on BACnet
®
MSTP (SA or FC) Buses. Before operating
FX-PC controllers on a bus, you must set a valid and unique device address for each controller on
the bus.
Set an FX-PC controller’s device address by setting the positions of the switches on the Device
Address DIP switch block at the top of the controller (Figure 2). Device addresses 4 through 127 are
the valid addresses for these controllers.
The DIP switch block (Figure 9) has eight switches numbered 128, 64, 32, 16, 8, 4, 2, and 1. Switches
64 through 1 are device address switches. Switch 128 is a mode switch that enables an FX-PC
controller to operate on an FX-ZFR/ZFR Pro Series Wireless Field Bus. Switch 128 must be set to OFF
for all hard-wired SA and FC Bus applications. Set Switch 128 to ON for wireless FC Bus applications
only.

Note:
FX-PC Series Controllers ship with Switch 128 ON and the remaining address switches
OFF. This renders the controllers wired subordinate devices, which do not interfere on MSTP
Buses and do not interfere with bus operation. Set a valid and unique device address on the
controller before applying power to the controller on the bus.
To set the device addresses on a an FX-PC Series Controller:
1. Set all of the switches on the controller’s device address DIP switch block (128 through 1) to
OFF.
2. Set one or more of the seven address switches (64 through 1) to ON, so that the sum of the
switch numbers set to ON equals the intended device address. See Table 6 and Table 7 for valid
FX-PC controller addresses. Set the highest number switch that is less than or equal to the
intended device address to ON. Then continue setting lower numbered switches until the total
equals the intended address. For example, if the intended device address is 21, set Switch 16 to
ON first, then set Switch 4 ON, followed by Switch 1 (16+4+1=21). See Figure 9.
3. Set Switch 128 to ON only for controllers on an FX-ZFR/ZFR Pro Series Wireless Field Bus
application. For all hard-wired SA and FC Bus applications, ensure that Switch 128 is set to OFF.
Note:
Do not connect a wirelessly enabled FX-PC controller to a wired FC Bus.
Refer to the
FX-ZFR Series Wireless Field Bus System Technical Bulletin (LIT-12011660)
for more
information on device addresses in wireless applications.
