YOKOGAWA CENTUM CS 3000 Integrated Production Control System

The Advanced Process Control Station (APCS) is a personal computer (PC) connected to the V net and applied to advanced process control and efficiency improvement.

Generic Subsystem Gateway Package (GSGW)

GSGW is a PC connected to V net. It uses OPC servers for subsystems, facilitating subsystem data acquisition and setting without creating specific communications programs.

Exaopc

This provides OPC Server functions to enable applications in a supervisory PC to access CENTUM CS 3000 data. It provides a link between control layer and business data processing layer.

Business Information PCs and Supervisory Computers

These can run MES and ERP integrated business management software. They can access the DCS via Exaopc or CGW.

Safety Instrumented System (ProSafe-RS)

ProSafe-RS is a dedicated system to prevent probability and spread of accidents when it is used as an interlock device, emergency shutdown system and fire and gas protection.

Safety Engineering PC (SENG)

This is a component equipped with engineering, test and maintenance functions to generate system and manage maintenance for safety control station (SCS).

Safety Control Station (SCS)

This is a safety controller that executes logics for systems including interlock, emergency shutdown and fire and gas protection.

V net

The V net real-time control system bus links stations such as FCS, HIS, BCV and CGW. Dual-redundant V net support is standard.

Ethernet

Ethernet is used to link HIS, ENG and supervisory systems. It is also used for transferring data files to supervisory computers, and for HIS data equalization.

Fieldbus

The FOUNDATION Fieldbus is a multidrop digital communications bus for field instruments, and is expected to replace the conventional 4 to 20 mA analog interface.

2.2 System Specifications

CENTUM CS 3000 is a flexible system that can handle everything from small to quite large systems.

System Scale

The CENTUM CS 3000 system specifications are as shown below:

• No. of tags that can be monitored: 100,000 tags (expansible up to 1,000,000 tags)

• No. of stations that can be connected: 256 stations (max. 16 domains, 64 stations per domain) – however, HIS is limited to a maximum of 16 stations/domain.

Domain

A domain is a logical V net bus segment. You can use a Bus Converter to link CENTUM CS 3000 domains, or link to previous systems (CENTUM CS, CENTUM-XL, CENTUM CS 1000, µXL etc.). Support will be provided for integrating CS 3000 with previous systems.

Migration from CENTUM CS 1000 to CS 3000

Easy engineering operation can migrate the existing CENTUM CS 1000 system to the CENTUM CS 3000 system.

Single control bus is available when the CENTUM CS 3000 Entry class system is migrated from the CENTUM CS 1000 system. In that case, Ethernet is not required.

2.3 Human Interface Station (HIS)

2.3.1 Console Type HIS

The console type HIS is composed of a console assembly and a general purpose PC. It is a new type of human interface station that can utilize the latest PC technology while succeeding the operability and functionality of the DCS.

It can be composed of dual stacked LCD, touch panel function, eight-control-key operation keyboard, and auxiliary contact I/O, and a number of console type HISes can be installed in a row.

There are two types of console type HISes: one is enclosed display style console type HIS, the appearance of which is usual style, and another is open display style console type HIS, which is composed of LCD and the configuration of which is selectable.

2.3.2 Desktop Type HIS

The Desktop Type HIS uses a general purpose IBM PC/AT compatible.

2.3.3 Operation Keyboard

The dust- and drip-proof operation keyboard has functionally arranged flat keys, which enables one-touch operation. The keyboard is available in two types: one is designed for eight-control-key operation for use with console type HISes, and another for one-control-key operation for use with both console type HISes and desktop type HISes.

2.4 Field Control Station (FCS)

The hardware architecture of the Standard Type Field Control Station for FIO (KFCS), the Enhanced Type Field Control Station for FIO (KFCS2), the Standard Type Field Control Station for RIO (LFCS), the Enhanced Type Field Control Station for RIO (LFCS2), and the Compact FCS (SFCS) is described below.

KFCS, KFCS2:The Field Control Unit (FCU) and the node are connected using ESB(Extended Serial Backboard) or ER(Enhanced Remote) bus.

FFCS:An FCS in which the FCU and a node unit are combined.

LFCS, LFCS2:The FCU and the node are connected using RIO bus.

PFC-H/-S/-E:The FCU and the I/O units are connected to the same backplate.

2.5 I/O Module Nests and I/O Modules

This section describes input modules, which convert process signals to digital data format used in the FCS, and output modules, which convert the digital data to analog or contact signals.

For I/O modules, there are the Fieldnetwork I/O (FIO), which are compact and consist of various lineup, and the Remote I/O (RIO), which have many installation bases.

2.5.1 Fieldnetwork I/O (FIO)

The FIO modules are used in the FCS for FIO. They are compact and consist of the lineup of abundant variety, such as the connector types, the isolation types, and so forth, to correspond flexibly to the applications.
