Problems  Cooling water pump equipment

Detecting the signs of cooling water pump failure

in various places in the plant

▲ Cooling water pumps are used in various

places in the plant.

Deterioration of the rotating equipment and

other components that make up the cooling

water pumps can lead to failure of the pumps.

Furthermore, if the cooling water pumps fail

and the cooling water temperature cannot be

maintained, the equipment that needs to be

cooled may also be damaged.

▲ Cooling water pumps are located in various

places in the plant, which require many

man-hours to inspect.

 GENERAL

This document describes the system configurations,

development/maintenance, software 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.
