In late 1994, the path of fieldbus took a new, promising direction. Two parallel supplier consortiums-the InterOperable Systems Project (ISP) and WorldFIP North America-merged to form the Fieldbus Foundation.
Fieldbus Foundation – Device Data Networks
‘This advanced digital communication solution was designed from the ground-up to support mission-critical control applications where the proper transfer and handling of data is essential. Foundation technology was created to replace incompatible networks and systems with an open, fully integrated architecture for information integration and distributed, real-time control across the enterprise.”
High Speed Ethernet (HSE) is ideally suited for use as a control backbone. Running at 100 Mbit/s, the technology is designed for device, subsystem and enterprise integration.
Foundation technology is the world’s leading digital protocol for process automation.Industrial network communication system for real-time distributed control. In the Technical Reference area you will find information on Design, installation and operation of Foundation-based plant automation systems….
Foundation Fieldbus H1 uses twisted pair or fiber media to link devices and the controller. Upto 32 Nodes on one port/point.
“Fieldbus is an all digital, two-way multi-drop communications link among intelligent smart field devices and automation systems. FOUNDATION Fieldbus is the Local Area Network (LAN) for instruments used in process automation with built-in capability to distribute the control application across the network.”
Here is a Fieldbus Device – Temperature Head Transmitter
Endress + Hauser – TMT85 – The iTEMP® TMT85 is a head transmitter for assembly in a terminal head DIN form B with 2 sensor inputs for resistance thermometers in 2-wire, 3-wire or 4-wire connection, thermocouples, voltage and resistance transmitters.

Some Facts –
Modbus Protocol is a messaging structure developed by Modicon (Schneider Electric) in 1979. It is used to establish master-slave/client-server communication between intelligent devices. It is a de facto standard, truly open and the most widely used network protocol in the industrial manufacturing environment.
The semiconductor industry has implemented a Network Communication Standard and an Object Messaging Protocol using Modbus TCP/IP. This allows SEMI Sensor Bus compatible sensors to communicate with each other using Modbus TCP/IP.
The mMINT (Modbus Master INCOM Network Translator) Module is an Eaton accessory product that will provide communication between a Modbus RTU network and an INCOM network.
The mMINT module is a slave device on the Modbus network and as such requires a master that will exchange register objects with the mMINT module. 32 products can be connected to INCOM network port (246 unique addresses maximum).
