Yokogawa CP451-10 Processor Module

01

Product Overview

Processor & control station

The CP451 processor module provides the processing function for Yokogawa AFV10-series Field Control Units used in CENTUM VP. The field control station connects the field-control system to its configured I/O node units through ESB or ER bus interfaces.

In a dual-redundant configuration, the FCU uses two CP451 processor modules. The host unit, processor arrangement, bus interface modules and control-function software must match the installed system design.

Associated FCU models AFV10S and AFV10D
Control network Dual-redundant Vnet/IP interface
Connectable node units Up to 14 node units per FCU in total; ESB Bus Node Units are limited to 9 or fewer
Control-function software LFS1500 for the AFV10-series Field Control Unit
Node expansion LFS1550 Application Capacity Expansion Package can increase node-unit capacity where required. The /NDEL node-unit expansion license is required for a node unit.
Power supply modules PW481, PW482 or PW484; two modules for a dual-redundant power-supply arrangement
ESB bus connection EC401 ESB Bus Coupler Modules are installed in slots 7 and 8 for a dual-redundant processor configuration. For a single ESB configuration, EC401 is installed in slot 7 and slot 8 remains empty.
ER bus connection EB401 ER Bus Interface Master Module is used for connection to ER Bus Node Units. In a single configuration, it is installed in an odd-numbered slot, with the slot immediately to its right left empty.
Sequence of Events Manager For SEM use with Vnet/IP, AFV10-series hardware must be Style 2 or later.

FCU-level configuration data applies to the AFV10-series system and should not be interpreted as individual CP451 module ratings.

System Configuration

FCU & node connections

The AFV10-series Field Control Unit operates as part of a Field Control Station. ESB Bus Node Units connect through EC401 bus coupler modules; ER Bus Node Units connect through EB401 interface modules.

For a dual-redundant processor arrangement, the processor pair and the relevant bus-interface arrangement must be configured together. Node expansion also depends on the applicable software package and system configuration.

Bus interface and configuration details

ESB bus: EC401 is installed in slots 7 and 8 when the processor modules use a dual-redundant configuration. For a single ESB configuration, install EC401 in slot 7 and leave slot 8 empty.

ER bus: EB401 is installed in an odd-numbered slot for a single configuration, leaving the slot immediately to its right empty.

Node expansion: LFS1500 is the control function for the AFV10-series FCU. LFS1550 can expand node-unit capacity beyond the base configuration.

Application & Failure Scenarios

Maintenance context

Processor replacement

Relevant when a CP451 processor is diagnosed as faulty or requires planned replacement in an AFV10-series FCU.

Redundant processor maintenance

For dual-redundant installations, confirm the active and standby module status and follow the site-approved maintenance sequence before replacing a processor.

Control station disruption

A processor fault can affect field-control execution. The resulting process impact depends on the FCU configuration, redundancy state and affected control functions.

05
