A FOUNDATION FIELDBUS System


4-20 mA

Discrete I/O

SYSTEM302 - Linking Devices


Linking Devices

WHAT IS A Linking Device?


LINKING DEVICES

  • A Linking Device Connects:

    • Fieldbus High Speed Ethernet

    • H1 Foundation Fieldbus Networks

  • Configured by Any FF Configuration Tool

Linking Device

FIELDBUS H1


LINKING DEVICES

MAIN FEATURES


LAS

Organizes the communication, Passing the token.

Fieldbus Ethernet

DFI302

“DFI302”

“SYSTEM302’s Linking Device !”


DFI302

“DFI302”

“Much More Than Linking Device !”


Distribution and Scalability

  • Unique Distributed Modular Design

  • Several Parallel Processors working together, as ONE!!

  • Unlimited Expandability:

    • Unlimited I/O

    • Unlimited Control Capability

    • Extreme Control Performance


DFI302 PROCESSORS

Each DFI302 PROCESSOR Handles:

  • 256 Conventional Points (512 Points with I/O Coprocessor)

  • 4 FF H1 Networks (Up to 64 Foundation Fieldbus Field Devices)

  • 4 LAS

  • 1 FF HSE Port

  • 1 Modbus Gateway Network (As-i Bus, DeviceNet, Profibus to come)

  • 100 Fieldbus Foundation Function Blocks


DISTRIBUTED ARCHITECTURE
