YOKOGAWA CENTUM CS 3000 Integrated Production Control System

Field Wiring Using Pressure Clamp Terminals

A field signal cable, with its end uncovered, can be connected directly to an analog or digital I/O module equipped with the pressure clamp terminal block. Two to three signal cables can be connected for every I/O channel.

Field Wiring Using KS Cable Interface Adapter

An analog or digital I/O module equipped with the KS cable interface adapter can be connected with the terminal board using the KS cable and field signal cables are connected to the terminal board with M4 screws.

2.5.2 Remote I/O (RIO)

The RIO modules are used in the FCS for RIO and Compact FCS. They are field-proven by the many installation bases, and designed basically by the isolated channels and M4 screw connections. The RIO modules are installed in the I/O module nests.

I/O Module Nests

I/O Modules Nests are available in the following types:

• AMN11: Nest for Analog I/O Modules

• AMN12: High-Speed Nest for Analog I/O Modules (for LFCS only)

• AMN21: Nest for Relay I/O Modules

• AMN31: Nest for Terminal-type I/O Modules

• AMN32: Nest for Connector-type I/O Modules

• AMN33: Nest for Communication Modules

• AMN34: Nest for Multipoint Control Analog I/O Modules

• AMN51: Nest for Communication Cards and Ethernet Communication Modules (for Compact FCS only)

• AMN52: Nest for Profibus Communication Module (in Compact FCS only)

I/O Modules

Input modules convert process signals to the digital data format used in the FCS. Output modules convert the digital data format used in the FCS to analog or contact signals. A list of I/O Modules is shown below:

Analog I/O Module

An analog I/O module is installed in Model AMN11, Nest for Analog I/O modules. Up to 16 I/O modules are installed in one nest. Signal cables are connected by M4 screws to the terminals of analog I/O module nest. For each I/O channel, two signal cables or three (for RTD) are connected.

Terminal Type Digital I/O Module

Up to two terminal type digital I/O modules can be installed in one Model AMN31 Nest for Terminal-type I/O Modules. Signal cables are connected by M4 screws to the terminals of modules. For each I/O channel, one or two signal cables are connected.

Connector Type Digital I/O Module

The Connector Type Digital I/O Module is installed in the Nest for Connector-type I/O Modules (AMN32). Up to four modules are installable in one nest. To connect to the MUB/MUD Terminal Board or TE16/TE32 Terminal Block, a KS2 cable is used for ADM11C and ADM51C 16-point modules and a KS9 cable for ADM12C and ADM52C 32-point modules.

Signal cables from field devices are connected by M4 screws to the terminal board or terminal block.

One or two signal cables are connected to each I/O channel.

Multipoint Control Analog I/O Module

AMC80 Multipoint Control Analog I/O Module is installed in the Nest for Multipoint Control Analog I/O Modules (AMN34). Up to two modules are installable in one nest. One module can process 8 inputs and outputs for control. Two modules installed in one nest may separately process different inputs and outputs or be dual-redundant. A KS1 cable connects the module to the MHM Signal Conditioner Nest. Compared with analog I/O modules, cost per point is less these for multipoint modules.

Terminal Type Multiplexer Module

The terminal type multiplexer module is installed in the Nest for Terminal-type I/O Modules (AMN31). Up to two modules can be installed in one nest. Signal cables are connected by M4 screws to the terminals of the module. Two or three signal cables are connected for each I/O channel.

Connector Type Multiplexer Module

The connector type multiplexer module is installed in the Nest for Connector-type I/O Modules (AMN32). Up to four modules can be installed in one nest. Using a KS2 cable (or a KU2 cable), connect it to Signal Conditioner Nest, MUB/MUD Terminal Board or TE16/TE32 Terminal Block.

Connect signal wiring from the field to the terminals of the terminal board or the terminal block with M4 screws.

Relay I/O Module

The relay I/O module is installed in the Nest for Relay I/O Modules (AMN21). Only one module is installable in one nest. Signal cables are connected to the terminals of the module with M4 screws. Two or three signal cables are connected for each I/O channel.

3. Operation and Monitoring Functions

Windows-Based Open Interface

The HIS software runs on a Windows based general purpose PC. Not only CENTUM CS 3000 HIS software but also general Windows application software (such as Microsoft Excel) can be run on the machine. In addition, open software interface OPC (OLE for Process Control) is supported. You can use the operator station not just for operating, but can also run office applications on it to write reports and memos, and to analyze process data.

Support for Latest PC Hardware

Personal computer (PC) technology is progressing very quickly. CPU and network speeds are increasing, CPU and memory prices are falling. Since a general purpose PC (IBM PC/AT Compatible) is used, you can incorporate the latest hardware in your system.

Enclosed Display Style Console Type HIS

The Enclosed Display Style Console Type HIS is composed of a console assembly and a general purpose PC. It is a new type of human interface station.
