YOKOGAWA FCN/FCJ Autonomous Controller

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

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.

FCJ

FCJ is an all-in-one controller with a built-in I/O interface — ideal for installing inside machine equipment as well as configuring a distributed system. Its control network can be duplexed. For hardware details, refer to FCJ Autonomous Controller Hardware, GS 34P02Q11-01E.

FEATURES

l High Performance

• Applicable to a variety of processes, from sequence control processes to analog control processes.

• Intercommunication with other autonomous controllers or other equipment for inter-linked control actions, in addition to stand-alone operation.

• Using Versatile Data Server Software (VDS) or Supervisory Systems (FAST/TOOLS) together allows a system with enriched operation and monitoring functions to be built up.

• An FCN/FCJ OPC server for Windows can be used for accessing the data of an FCN/FCJ from an OPC (OLE for Process Control) client on a PC.

• Java-enabled — enables users to implement various applications, including displaying images on a Web browser, saving data files, transferring files using the FTP protocol, sending/receiving e-mails and public network connection using the PPP protocol.

With InfoWell, applications such as web browsers and e-mail communications can be utilized without programming.

High Reliability

• RAS features (CPU self-diagnostics, temperature monitoring, I/O diagnostics, and more)

• Memory with error-correcting code (ECC)

• Low heat dissipation, eliminating the need for a cooling fan

• The Ethernet control network, CPU, power supply module, and SB bus (FCN local bus) can all be duplexed for an FCN-100.

• The control network can be duplexed for an FCJ.

Engineering Efficiency

• Five IEC 61131-3 compliant programming languages are supported, enabling the user to selectively use these languages according to their purposes of use and applications.

• Control logic can be encapsulated into software parts for reuse, allowing efficient and quality system configuration.

• Application Portfolios packed with Yokogawa’s application expertise, enable easy implementation of advanced functions, including control-loop instrument blocks and communication with non-Yokogawa PLCs.

Easy Maintenance

• Online download function allows a control application to be modified during system operation

• All modules are hot-swappable with an FCN-100.

CONFIGURATIONS

System Configurations

Both FCN and FCJ are 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 or FCJ

• A system in which FCNs and/or FCJs 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 FCNs and/or FCJs are interlinked with VDS, FCN/FCJ OPC Server or FAST/TOOLS (up to a total of 4 VDSs, FCN/FCJ OPC Servers and FAST/TOOLS can be connected).

Using a communication portfolio within an Application Portfolio allows an FCN/FCJ to communicate with other kinds of controllers and devices.

Development and Maintenance of FCN/FCJ

Figure Development and Maintenance of FCN/FCJ A PC/AT-compatible computer is used for development and maintenance of applications for an FCN and FCJ. Resource Configurator is a tool program to be installed in the computer used for maintenance, and is used to make the FCN/FCJ hardware settings.

The user can access FCN and FCJs 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 for an FCN/FCJ. Logic Designer requires a license to run.

These tool programs are supplied on a DVD-ROM.
