Hardware
The FLN Controller consists of the following two major
components:
• Enclosure Assembly and FLN Controller service
box⎯Enclosure Assembly houses internal
components and FLN Controller service box
supplies power receptacles for the plug in power
packs, Controller Board and modem.
• Controller Board⎯contains the main processor
and communications. The Controller Board
supports both dial-out and BLN peer-to-peer
networking capabilities.
Enclosure Assembly
The Enclosure Assembly includes mounting brackets
for the Controller Board and power receptacles. The
enclosure assembly houses the electronic
components.
The Enclosure Assembly is constructed of metal to
accommodate secure conduit fittings and protect
components against electrical transients.
The hinged front door has a see-through view panel to
allow the user to see the status of the Controller Board
LEDs.
The Enclosure Assembly has three unswitched 115
Vac outlets (or two unswitched IEC 230 Vac outlets)
for powering the Controller Board and accessory
devices such as modems and Portable Operator's
Terminals.
Controller Board
The Controller Board contains a multi-tasking
processor for communication to FLN devices,
providing program execution, alarm management and
operator interface. Three FLN trunks for
communication with up to 96 FLN devices can be
connected to the Controller Board.
Two RS-232 operator terminal ports with quick connect
phone jacks (RJ-11) are included on each Controller
Board to allow use of operator devices such as a
simple display terminal, laptop computer, printer or
modem.
The RAM memory of the Controller Board is 1 MB
RAM and is expandable to 2 MB RAM.
The program and database information stored in the
FLN Controller panel RAM memory is battery-backed
for 60 days in the event of an extended power failure.
This eliminates the need for time-consuming program
and database re-entry in the event of an extended
power failure. The lithium battery is also field-
replaceable. The Controller Board has a “battery low”
indicator LED to advise when battery replacement is
necessary, and sends an alarm to selected printers or
terminals.
The firmware operating system is stored in non-volatile
flash ROM memory. Flash ROM is easily updateable
at the job site. This provides for ease of upgrade as
new “firmware” updates are made available.
Brownout protection and power recovery circuitry
protects the Controller Board from power fluctuations.
Building Block Architecture
Start with an FLN Controller and add a combination of
TECs, UCs, DPUs and DPMs on the FLN for
distributed stand-alone control of mechanical
equipment. Up to 96 distributed FLN devices can be
connected to each FLN Controller.
In this stand-alone configuration, the FLN Controller
can fulfill all requirements of a supervisory network
coordinator, managing operation schedules, alarms
and communication for the FLN devices.
Up to 100 FLN Controllers can connect and
communicate on a peer-to-peer network.
Global Information Access
Each FLN is equipped with two RS-232 operator
terminal ports. These ports support the connection of a
modem, simple display terminal, laptop computer, or
printer. Devices connected to the FLN Controller RS-
232 port provide global information access.
Multiple Operator Access
Multiple operators can access the network
simultaneously. This is useful if a local operator is
accessing the system while a remote operator is
accessing the system via modem. Multiple operator
access ensures that alarms are reported to an alarm
printer while an operator accesses information from a
local terminal.
Menu Prompted, English Language
Operator Interface
The FLN Controller has a simple, menu driven English
Language Operator Interface that provides, among
other things:
• Remote point monitoring and display
• Remote point commanding
• Historical trend collection and display for multiple
remote points
• Time-of-Day equipment scheduling
• Program editing and modification via Powers
Process Control Language (PPCL)
• Alarm reporting
• Built-in Direct Digital Control Routines
