YOKOGAWA FIO System (compatible with Vnet/IP) Hardware Specification Manual

Overview

This document is the general specification sheet for Yokogawa Electric's FIO (Fieldnetwork I/O) system (document number: GS 33K50F10-50E), updated to version 8 in September 2014. Its core purpose is to guide the deployment, module selection, and installation of the system in CENTUM VP (Vnet/IP). As a field I/O solution, the FIO system is connected to the field control unit (FCU) through ESB/optical ESB/ER bus, supporting dual redundancy configuration and adapting to the signal acquisition and control needs of various industrial scenarios. The module types cover all categories such as analog, digital, and communication, and meet multiple international safety and EMC standards.

System architecture and bus specifications

（1） Overall architecture

The FIO system is based on the core architecture of "FCU+node unit+bus". The node unit includes a power module, a bus interface module, and an I/O module, which can be extended in a chain/star configuration through an optical ESB bus relay unit (ANT10U). It supports dual redundancy configuration (power supply, bus, I/O module) to ensure high availability of the system.

（2） Three major bus core specifications

Bus type suitable for FCU transmission rate, transmission distance support, node unit topology structure

ESB bus AFV30 /AFV40 /AFV10  128 Mbps ≤ 10m ANB10  bus type

Optical ESB bus AFV30 /AFV40  128 Mbps up to 50km (ANT411 relay) ANB11 , ANT10U chain/star type

ER bus AFV10  10 Mbps YCB141: ≤ 185m; Hybrid cables must meet the formula limit ANR10  bus type
