Risk of Electric Shock.
Disconnect the power supply before making electrical connections. Contact with components carrying
hazardous voltage can cause electric shock and may result in severe personal injury or death.
FX80 Supervisory Controller Installation Instructions2
Warning
Risque de décharge électrique.
Débrancher l'alimentation avant de réaliser tout branchement électrique. Tout contact avec des
composants conducteurs de tensions dangereuses risque d'entraîner une décharge électrique et de
provoquer des blessures graves, voire mortelles.
Important: Use copper conductors only. Make all wiring in accordance with local, national,
and regional regulations. Do not exceed the FX80 Supervisory Controller’s electrical ratings.
Important: Remove all power to controller before attaching (plug in) or detaching (unplug)
any option card module, to prevent possible equipment damage.
Static Discharge Precautions
Static charges produce voltages high enough to damage electronic components. The
microprocessors and associated circuitry within the devices are sensitive to static discharge.
Note: Removal of the cover is not required. The controller contains no configurable or user-
serviceable items (such as jumpers).
Mounting
Mount the controller in a location that allows clearance for wiring, servicing, and module removal.
Physical mounting
The following applies when you physically mount the unit.
• Horizontal mounting is strongly recommended to achieve maximum heat dissipation and meet
the operating temperature upper limit. Any other mounting orientation reduces the upper limit.
• Mounting on a 35 mm wide DIN rail is recommended. The controller's unit base has a molded
DIN rail slot and locking clip, as do option modules. DIN rail mounting ensures alignment of the
connectors between the devices.
• Up to four option modules are supported.
• Dimensions of a unit appear in the following figure.

Wiring
Earth ground and power
Earth grounding provides protection from electrostatic discharge or other forms of EMI.
5FX80 Supervisory Controller Installation Instructions
Figure 5: Earth ground and power options
Depending on the power source used:
•2.1 (AC): Dedicated 24 V transformer required, with neither side of the transformer secondary
tied to ground.
•2.2 (DC): Polarity is not important (uses onboard diode bridge), with neither leg tied to ground.
•2.3 (Wall-mount AC adapter, FX-SC8XPS-0) instead of wiring 24 V to 2-position connector. Do not
use the wall-mount AC adapter simultaneously with power wired 2-position connector.
Wiring earth ground and power
Important: Before making power terminations, de-energize the 24 V power source. Do not
restore power until completing all other mounting and wiring.
Important: A grounding point must be present nearby.
1. Install the included earth ground wire to the controller's earth ground spade lug, and
terminate the other end to a nearby earth ground.
2. Unplug the controller's 2-position power connector plug and terminate the 24 V supply source
(AC or DC) to the connector. Leave the connector unplugged.
Communications wiring
FX80 Supervisory Controller Installation Instructions6
Figure 6: Communications ports on the Controller
Table 1: Communications ports on the Controller
Callout Description
1 RS-485 ports and bias switches
2 Wi-Fi adapter, settings switch, and antenna
3 Ethernet ports, 10/100-Mbit, RJ-45
4 Earth ground and 24 V power input
Wi-Fi
An integral Wi-Fi adapter provides wireless connectivity using the IEEE 802.11b/g/n standard, and
provides an RP-SMA coax antenna connector.
The Wi-Fi configuration switch sets operation as follows:
•OFF - (Default, middle) Wi-Fi adapter is disabled.
•ACC - Controller provides operation as a Wi-Fi access point for up to 20 clients.
•CLT - Controller operates as a client to an existing 802.11b/g/n router or access point.
Note: By default, the Wi-Fi software is disabled. You must enable the WiFi within the software
before it becomes available.
RS-485 wiring
On the controller's top side, two RS-485 ports operate as COM1 and COM2. Each port is capable of
up to 115,200 baud, and uses a 3-position, screw terminal connector.
Use shielded, twisted-pair, 18-22 AWG cabling to wire in a continuous daisy chain fashion to other
RS-485 devices: minus-to-minus, plus-to-plus, and shield-to-shield. Connect the shield wire to earth
ground at one end only.
For more information about wiring guidelines, refer to FX-PC Series Controllers MS/TP
Communications Bus Technical Bulletin (LIT-12011670).
7FX80 Supervisory Controller Installation Instructions
Figure 7: RS-485 wiring example
Table 2: RS485 wiring example
Callout Description
1 RS-485 port A (COM1) is often used to support a trunk of LP-FXRIO16-0 modules. Do
not mix LP-FXRIO16-0 modules with other types of RS-485 devices on the same RS-485
trunk.
2 RS-485 port B (COM2) supporting a network of other field devices using RS-485 field
communication.
3 RS-485 devices on the same network should use the same protocol and baud rate. Up
to 32 or more devices may be supported depending on device specifications.
RS-485 bias switches
Each RS-485 port has an adjacent 3-position biasing switch, with these settings:
•BIA - (Default, middle) Controller provides RS485 biasing, but without a termination resistor.
FX80 Supervisory Controller Installation Instructions8
•END - Both RS485 biasing and a termination resistor are provided by the controller.
•MID - No RS485 biasing or termination resistor is provided by the controller.
Often, adding RS-485 biasing can improve communications by eliminating indeterminate idle
states.
Note: FX-PC controllers implement biasing. When using RS485 for BACnet MS/TP with FX-PC
controllers, we recommend using the MID position (with FX-PC controllers at the ends of the
trunks with their EOLs set). The BIA position is not required for an all FX-PC controller trunks.
For more information, refer to the FX-PC Series Controllers MS/TP Communications Bus Technical
Bulletin (LIT-12011670).
Ethernet wiring
Two RJ-45 10/100-Mbit Ethernet connectors are labeled PRI (LAN1) for primary, and SEC (LAN2) for
secondary. Use a standard Ethernet patch cable to an Ethernet switch.
The factory-default IP address for PRI is 192.168.1.149. The default subnet mask is 255.255.255.0.
By default, the SEC (LAN2) port is disabled.
Setup and adjustments
Power Up and initial checkout
1. Apply power. To do this, do one of the following:
- Insert the 2-position 24 V power connector plug.
- Insert the barrel plug of the wall-mount AC adapter (FX-SC8XPS-0).
2. Check the STAT (Status) and BEAT (Heartbeat) LEDs.
When power is applied, the green STAT LED flashes. This LED indicates that the system is work-
ing, with power applied. During startup, the BEAT LED may blink at 1 Hz with a 90/10 percent
on/off duty cycle. When startup completes, the platform daemon is started, and the normal 1
Hz flash at 50/50 percent on/off duty cycle of the BEAT LED returns.
LEDs
The controller provides a number of status LEDs. All but one of the LEDs are visible with the front
access door closed.

2RS-485 A (COM1) - Transmit (TX) and Receive (RX)
3RS-485 B (COM2) - Transmit (TX) and Receive (RX)
4STAT (Green) - Remains lit when controller is powered
5BEAT (Yellow) - Heartbeat, normally 1 Hz 50% duty cycle
6Secondary Ethernet - SEC (LAN2) Link and Activity
7Primary Ethernet - SEC (LAN1) Link and Activity
8(Behind door) BACKUP (Green) - Typically off
If the BEAT LED stays on constantly, does not light, or blinks very fast, have your ABCS Distributor
contact the FSC or your appropriate technical support group.
Important: The 1 Hz, 90/10 percent on/off BEAT flash at startup also occurs during other
critical operations, such as a firmware upgrade to the controller or any attached modules.
To be safe, do not remove power from the controller while its BEAT LED flashes with a 90/10
percent on/off duty cycle. Wait for the normal (50/50 percent) flash to return before removing
power.
Remove or replace the microSD flash memory card
If necessary, you may need to remove or replace microSD flash memory card.
