Applications of Controller Technology |
Present View and Outlook for Applications of Controller Technology
Masakatsu Hishinuma, Hideo Masumoto, Yasushi Ishii
The MICREX-SX series (SX) of integrated controllers incorporate
advanced technology such as high-speed processing and are being
applied in a wider array of fields. This paper describes flexible system
solutions and the software modularization that leverage the SX's special
features (higher speed and open network) and which support the
growing range of applications. Also presented are an actual application
example, development techniques such as for the block engineering
used in an application, and other components that support applications.
New Features of PLC Programming Tool "D300win Ver.3"
Masayoshi Matsumoto, Koji Fukushima
The D300win, a program development and support tool that conforms
to international standard IEC61131-3, has leveraged the flexibility
of software products to further enhance and expand various functions,
performance and operability, and together with the MICREX-SX
series, has been well received following its introduction to the market.
Its growing range of applications, due to the recent support of programmable
controller open networks and its use in combination with servo
motors and inverters, together with demands for a development environment
that enhances productivity of control programs having
increasingly advanced functions, higher complexity and larger scale,
have led to the development of a Ver.3 that is even easier to use than
the prior Ver.2. This paper describes the major features of the D300win
Ver.3.
"HEART Series" of Innovative Engineering Tools
Minoru Yoshino, Masaharu Yamaguchi, Tomomasa Kudoh
The HEART series of support tools automatically generate the
control software for a programmable controller (PLC) or distributed
control system (DCS) from control specifications that have been created
with Excel or Visio office automation software. The HEART
series is also provided with a function to test those specifications. The
generated software operates according to the abovementioned specifications,
eliminating the need for design, coding and debugging steps.
The HEART series enables the efficient generation of high-quality
software.
Application of Controllers to Motion Control Systems
Tadakatsu Aida, Yoshiaki Shimada, Kenji Tajiri
This paper presents three types of motion control systems being
proposed by Fuji Electric: network, motion controller (MC) module,
and function block (FB) systems. For the network system, a long-distance
distributed system comprised of servo amps having a built-in
positioning function is described. For the MC module system for multiaxial
use, a table format program editor/loader for controlling multiple
machines with an easy-to-understand, large-size motion program is
described. And for the FB system, concepts of the synchronous operation
system and of the electronic cam system are described.
Application of the MICREX-SX Series to Drive Control Systems
Yukio Inoue, Masahiro Kina, Mitsuhiko Togo
A characteristic feature of the MICREX-SX series (SX) of integrated
controllers is its use of a function block diagram (FBD) programming
language, whereby drive control elements are modularized
into function blocks (FBs), enabling highly efficient programming. This
paper presents three examples of application to a drive system. Also,
utilizing another characteristic feature of the SX series, its high-speed
bus, an example system that acquires and analyzes the control data for
drive units is also described.
Remote Monitoring and Maintenance Systems Based on the MICREX-SX Series of Integrated Controllers
Kazuhiro Fujita, Fumio Takahashi, Yoshinobu Hirao
On the shop floor and at manufacturing facilities, there is a strong
desire to realize efficient facilities management in order to achieve stable
and safe operation for the purposes of energy savings and cost cutting.
As a solution, Fuji Electric has been providing a remote monitoring
and maintenance system that utilizes IT. The application of IT has
developed rapidly and the technology has trended toward lower prices.
This paper presents an overview of the Fuji online adapter (FOA) that
uses public networks and the SX-Web module that uses an
intranet/internet for use in configuring a remote monitoring system
based on the MICREX-SX series of integrated controllers.
Application of Controllers to the Management System for an Office Building
Masahiro Maeeda, Yasunori Nagata, Yukio Fukui
In response to the information orientated trends of recent years
and with the goal of decreasing lifecycle costs, there is strong demand
that building management systems be able to control a greater variety
of devices and for the more widespread use of multi-vendors. In
response to these demands, networked technologies typified by
BACnet and LONWORKS, that are suitable for building management,
have led to control devices being compatible with open networks, and
greater industry-wide standardization. This paper introduces the development
of Fujitsu Ltd.'s building management system that supports
LONWORKS and utilizes the MICREX-SX series of integrated controllers.
An example of an actual delivered product, the standardization
method and applicable products are also described.
Application of Controllers to a Temperature Control System
Kiyoshi Miyaso, Masato Kawaura
This paper introduces a system that performs temperature control
via the application software for a programmable controller (PLC). A
temperature control system configured from standard PLC hardware
and using software components for PID control is presented. An inpanel
type temperature controller based on the MICREX-SX platform
is also introduced. The inpanel type temperature controller is developed
by Fuji Electric Instruments Co., Ltd., a member of the Fuji
Electric Group.
Application of Controllers to a High-speed Analog Data Logging System
Mitsunori Fukuzumi, Hideo Takahashi
A high-speed analog data logging system was built using the various
program functions and diverse peripheral equipment of the highspeed,
small-size MICREX-SX series of integrated controllers. The
configuration, features and example application of this analog data logging
system are described.
Application of Controllers to an Energy Monitoring System
Tsuneo Kiuchi, Masami Marubayashi
As protection of the global environment becomes of greater concern,
energy conservation laws are being revised and strengthened to
require that a greater effort be made across all business sectors to
reduce the levels of energy consumption. This paper introduces an
energy monitoring system that utilizes a controller to support the
diversified user needs for interfaces and measurement signals when
installing an energy monitoring system under the present conditions.
