slurries or low conductivity fluid, extremely stable

measurements can be realized.

Improved Minimum Conductivity

The newly designed AXF converter permits the

measurement of fluids with conductivity as low as 1µS/cm.

High-Speed Pulse Output “ ”

The pulse rate now goes up to 10.000 pps (pulse/

second) for use with high speed applications such as in

short time batch processes.

Versatile Input/Ouput Function for Integral Flowmeter

Integral type is also equipped with versatile input/output

function.

The AXF magnetic flowmeter series are sophisticated

products with outstanding reliability and ease of

operation, developed on the basis of decades of field

proven experience.

The combination of a replaceable electrode and the

diagnostic to defect adhesion level on the electrodes

dramatically improves maintainability.

The AXF employs the fluid noise free “Dual Frequency

Excitation Method” and the newly added “Enhanced Dual

Frequency Excitation Method” as an option for more

difficult applications to ensure greater stability and quicker

response.

Note: The “Dual Frequency Excitation Method” is

Yokogawa’s unique technology.

 FEATURES

●    FCN-based    Turbomachinery    Controller

The FCN autonomous controller can be applicable to a variety of processes from sequence control processes to

analog control processes. A wide variety of types of I/O modules are supported and a flexible system configuration

can be selected according to purpose.

Applying an FCN-based turbomachinery controller to the control of generator turbines or other turbomachinery such

as compressors also enables control of their ancillary facilities.

The CPU module, power supply, and communication can be made redundant for applications that require high

reliability.

●    Turbomachinery    I/O    Modules

Combined use of an FCN autonomous controller and turbomachinery I/O modules makes it possible to control and

protect turbomachinery such as turbines and compressors. With the STARDOM turbomachinery controller, a flexible

system can be constructed according to the scope of control and the installation space.

Of the turbomachinery control and protection functions, processing that requires high speed response is carried out by

the turbomachinery I/O modules. There are two types of turbomachinery I/O modules: a servo module that performs

high speed servo control in a cycle of 5 ms and a high speed protection module that performs a high speed protection

action in a fast scan (5 ms) or a standard scan (10 ms).

    FUNCTIONS

The primary functions of a turbomachinery controller comprise of regulatory control of the turbomachinery speed,

load, and fluid pressure, and so on, and protection of the turbomachinery from anomalies. Control and monitoring of

ancillary facilities can also be added if necessary.

●    Configuration    Types

There are two types of configuration for the STARDOM turbomachinery controller.

Type 1: Configuration with a FCN-RTU

Type 2: Configuration with a FCN-500

 GENERAL

This document describes the system configurations,

network and specifications, for two types of

autonomous controllers in the STARDOM: FCN with

NFCP100 CPU module and FCJ.  (FCN is an acronym

for field control node, and FCJ for field control

junction.)

Notation in this document:

• The term “FCN” refers to the module consisting type

autonomous controllers.

• The term “FCN-500” refers to the autonomous

controllers with NFCP501/NFCP502 CPU module.

• The term “FCN-100” refers to the autonomous

controllers with NFCP100 CPU module.

• The term “FCN-RTU” refers to the low power

autonomous controllers with NFCP050 CPU module.

• The term “FCJ” refers to the all-in-one type

autonomous controllers.

FCN-100 is a controller module consisting of CPU, I/O,

and other modules as necessary.  It supports a variety

of I/O modules, provides a highly reliable system with

duplexed power supply, CPU and control network

options as well as superb scalability.

For hardware details, refer to FCN Autonomous

Controller Hardware (FCN-100), GS 34P02Q12-01E.

 CONFIGURATIONS

l    System    Configurations

FCN-500 is locally mounted controllers to allow diverse

systems to be configured according to the individual

users’ work sites; however, the possible system

configurations can be broadly divided into three types:

• A system consisting of a standalone FCN-500

• A system in which FCN-500s are connected to

each other through the control network and perform

interlinked actions (up to a total of 15 FCNs and FCJs

can intercommunicate with one FCN/FCJ).

• A system in which one or more FCN-500s are

interlinked with VDS, FCN/FCJ OPC Server or FAST/

TOOLS.

VDS and FCN/FCJ OPC server, FAST/TOOLS can

be connected up to 8 units in total. The FCN/FCJ

OPC server counts as 2 units because the DA server

and AE server operate. The FAST/TOOLS with

duplexed network counts as 2 units.

Development    and    Maintenance    of    FCN-500

A PC/AT-compatible computer is used for development

and maintenance of applications for an FCN-500.

Resource Configurator is a tool program to be installed

in the computer used for maintenance, and is used to

make the FCN-500 hardware settings.

The user can access FCN-500s via a Web browser

from a PC to make detailed settings for the network

and so on, and to perform maintenance operations

such as database backup and restoration.

Logic Designer is a tool program for the development

of control applications (IEC 61131-3) for an FCN-500.

Logic Designer requires a license to run.
