9.0 SOFTWARE
CONTROL
9.1
Overview.
The furnace control system shall consist of an
. The OIT shall allow
operators to view and control furnace operation, store and retrieve production process recipes,
handle system alarms and log furnace events, and communicate with the PLC. The PLC shall
locally send and receive information to/from the OIT and process furnace IO (input/output) to
control the furnace.
9.2
.
The furnace controller (PLC) shall be a commercial 32-bit industrial controller that
provides real-time control and communication to the furnace IO. The controller shall provide
10/100 Mbps Fast Ethernet communication to the OIT PC. The furnace controller shall
generate and process all alarms and safety features. All sensor and control inputs and outputs
shall be optically isolated to insure integrity of the controller. In case of loss of communication
between the OIT and the controller, the controller shall continue to operate the furnace
normally until communication is re-established with the PC.
9.3
.
Operators communicate with the PLC is through an OIT (operator interface terminal)
graphical user interface running on a Windows-based PC located at the furnace. The PC shall
include a local PC monitor, keyboard and mouse at the system console mounted on top of the
furnace cabinet.
9.3.1
The OIT hardware shall include a WindowsXP™ Dell Optiplex™ managed-platform
computer (
).
9.3.1.1
The PC shall be equipped with a RAID Level 1 system consisting of two (2) mirrored
hard drives to provide ongoing automatic system data backup to insure continuous operation
and integrity of the furnace program, process recipes and data in case of hard disk drive failure.
9.3.1.2
The PC shall be equipped to store all operational software, user-defined recipes and
profiles for retrieval for archive or use in furnace operation.
9.3.1.3
The PC shall be equipped with an optical CDRW for software restoration and
archival storage.
9.3.1.4
The furnace and computer shall include and offer access to USB ports for easy
transfer of recipes and operation of temperature profiling systems.
9.3.1.5
The PC shall include a TCP/IP Ethernet port for communication with the furnace
controller.
9.3.1.6
The Furnace shall include a second TCP/IP port for providing network access and, if
internet enabled, factory diagnostic support. In addition to the second TCP/IP connection, a
modem shall be installed to provide a second method of remote factory diagnostic support.
9.3.2
The PC and monitor shall be wired directly to the furnace primary transformer thereby
bypassing the control system on/off switch. This unswitched arrangement allows reliable
startup and shutdown of the PC under the WindowsXP™ operating system, allows the PC and
monitors to be used without powering up the furnace, and extends PC life and reliability.
9.4
ProControl™ Furnace Software
9.4.1
The software shall consist of Logic and the OI. The PC shall contain the program and logic
that is downloaded to the PLC. On startup an OI compiled runtime program shall load and run
the Furnace graphical user interface software.
9.4.2
Logic.
The PLC shall use Flow Chart based logic consisting of two primary blocks. The
Operation block shall contain the basic program complete with multilevel case statements and
if-then-else logic and loops to reduce program size and increases speed. Condition blocks shall
contain additional program AND/OR conditions for furnace operation and feedback.
9.4.2.1
Conveyor speed
shall be regulated by a stand-alone motor speed controller, which
accepts commands from the control system. The motor speed controller in return shall provide
the control system with the actual speed of the motor. A separate interface shall be used to
