Product Description

Description

The Yokogawa AFV30S-S41251/HKU is a 19-inch rack-mountable Field Control Unit (FCU) designed as the core component of the control function within the CENTUM VP integrated production control system. It processes process operations, manages field communications over dual-redundant Vnet/IP networks, and handles local and remote I/O data through FIO interface configurations.

This single-processor module platform supports up to 8 I/O modules directly on the rack assembly and connects to up to 13 ESB bus or optical ESB bus node units. Equipped with dual-redundant power supply modules operating at 220-240 V AC, this unit incorporates an integrated House Keeping Unit interface (/HKU option) that outputs FCU fault contacts, monitors cabinet environmental conditions via the HK bus and optical ESB bus, and displays system alarms directly on the Human Interface Station (HIS).

Features

Serves as the central control processing unit for CENTUM VP Field Control Stations
Features dual-redundant Vnet/IP communication interfaces for high-reliability network integration
Configured with dual-redundant power supply modules for continuous operation
Accommodates up to 8 I/O modules and supports up to 13 connectable ESB/optical ESB node units
Integrated House Keeping Unit (/HKU) interface for cabinet environmental monitoring and fault contact outputs
Includes battery backup capable of maintaining main memory for up to 72 hours during power outages
Standard 19-inch rack-mountable form factor with 8-hole M5 mounting points

Applications

Process automation and control in CENTUM VP integrated production control systems
Centralized field control interfacing with remote FIO nodes over optical ESB and ESB buses
Real-time monitoring and fault diagnostic reporting via House Keeping Unit (HKU) networks

Installation Guidelines

Cabinet Mounting: Mount the unit on a standard 19-inch rack using M5x8 screws and the provided accessory insulating bushes (part number S9049PM).
Cabinet Enclosure Requirements: To meet safety standards and EMC requirements, install the control unit inside a keyed metallic cabinet.
ESB Bus Coupler Modules: Install ESB Bus Coupler Modules (EC401 or EC402) in slots 7 and 8 of the FCU to connect node units.
Optical ESB Bus Repeater Master Modules: When connecting remote nodes over optical fiber, install Optical ESB Bus Repeater Master Modules (ANT401 or ANT411) in pairs within slots 1 through 6, ordered from right to left.
Intrinsic Safety Partitioning: When using I/O modules with built-in barriers inside the unit, an insulating partition kit (Part No. T9083ND) must be installed.

FAQ

How long can the internal battery preserve the main memory during a power outage?

The main memory battery backup supports data retention for up to 72 hours, with a minimum recharge time of 48 hours.

How many external node units can be connected to the device?

A maximum of 13 node units (total sum of ESB bus node units and optical ESB bus node units) can be connected.

What is the function of the /HKU option on the field control unit?

The House Keeping Unit interface outputs FCU fault contacts, monitors cabinet environmental conditions over the HK and optical ESB buses, and displays system alarms on the HIS.

What cable specification is required for the Vnet/IP network interface connection?

The Vnet/IP network interface requires UTP cables rated CAT5e or better connected to a Layer 2 switch.
