A powerful, yet scalable system, with superior
reliability and flexibility, the ECS-1200 distributed control system
is the result of more than five decades of innovation and manufacturing
of control systems in hundreds of installations around the world. With
scalable architecture to match any size control requirement, each system
provides complete, fully integrated network and system control solutions
in any application or industrial setting.
Encompassing an extensive selection of
I/O cards for the simplest to the most complex operations, the ECS-1200
control system is fully redundant for confident operation during critical
control conditions. Linked through a high-speed, open architecture network,
the advanced microprocessor-based control system can perform all sequential
and modulating control functions including plantwide data acquisition,
monitoring, and display functions with superior integrity and maximum
data throughput. With the open architecture network, connection of foreign
devices and third-party software applications is easily achieved. Reduced
integration time and hardware costs eliminate communications cables
and dramatically improve configuration flexibility and maintenance facility.
HFC provides a full complement of system
engineering and programming services. In addition to the advanced control
and monitoring software packages, HFC applications engineers can uniquely
configure each control system to significantly improve plant efficiency
and profitability. The system can provide a diversity of field interfaces
ranging from 4-20ma analog input modules to remote fieldbus devices.
With modular design to allow easy system expansion plus the downward
compatibility of features to legacy systems, the end user's investment
is protected as the system evolves to meet the changing needs of the
The ECS-1200 distributed control system
consists of five major components: Multifunction Controllers, Input/Output
(I/O) modules, Applications Software, Industry Standard Communication
Networks, and the Advanced Operator Interface Workstations. These components
combine to deliver an exceptional process automation solution that not
only optimizes plant performance and efficiency, but also is an extension
of management's daily decision making tools.
Because scalability is necessary for both small and large systems, HFC
offers a variety of controllers that can be intermixed throughout the
system to optimize system configuration. With advanced, powerful digital
and analog central algorithms, the multifunction controllers can be
configured online or offline using a programming utility incorporating
simple function blocks for control applications.
The control system I/O modules are comprised of a complete family of
digital and analog input and output boards. The I/O modules provide
a host of advanced technological features offering a secure and dependable
interface to field devices. The intelligent I/O supports a multitude
of features such as built-in continuity monitoring, motive power, and
status feedback for complete plant control and monitoring functions.
Other significant features include separate power monitoring, independent
manual reset switches, jumper-selectable I/O link addresses, and a self-configuring
baud rate. Sophisticated diagnostics provide operators with a virtual
extension of their senses into the heart of the operation.
In addition to the vast array of standard
analog and digital I/O modules, specific functions such as thermocouple
and sequence of events monitoring, HSIM's (High-Speed Interface Modules),
and pulse input-output are available for specialized control and monitoring
Three workstation configurations make up the components of the control
room. Efficient plant operation is easily achieved through Microsoft®
Windows® 2000 based workstations: the operator workstation, the
engineering workstation, and the historical archiving system. With the
Windows® 2000 environment, all workstations support interactive
color displays, multi-window displays, and a standard library of symbols
to allow complete customization. To provide a real-time interactive
environment, the control room workstation displays are updated with
current values at a rate of once per second. Workstations are connected
to the system through industry-standard communication protocols, allowing
access to any database point in the system. Each system can be connected
to other computers and control systems on the network through the use
of a standard Ethernet LAN and TCP/IP link.
HFC incorporates an innovative approach to software design and integration
services that allow information obtained from local and remote I/O,
data links to other devices, or output variables from controls strategies
to be shared by other software applications and devices. Implementing
changes to the system logic as well as customizing logic for a specific
application is simple and does not require specific programming knowledge
or software training. A built-in programmable feature also allows construction
of the control system before operational logic is completed, minimizing
the cost of field logic changes. These design tools along with the industry
standard hardware and open architecture communications result in a high-speed,
reliable, and fully integrated system that is capable of meeting any
process control requirements.
The HFC communications network is the most flexible network available
today. The network accepts all systems and devices including PLC and
CEMS, and can support commercial software in addition to HFC software.
The redundant communications links between the controllers provide exceptional
data integrity and stability. The redundant 10Mb/sec C-link allows the
connection of multiple controller units and distributed control is supported
through high-speed fiber optic links to form an extremely well designed
and reliable communications network. For interface with our advanced
CRT operator and engineering workstations, high-speed, open architecture
technology provides a 100Mb/sec TCP/IP local area network (LAN). Communications
gateways and hubs enable easy connection to multiple workstations as
well as allow access to plant control operation from offsite locations.
