Modbus Communication Protocol Suite

Group of individuals and firms supporting and helping the implementation of Modbus communication protocol suite and the evolution to address architectures for distributed automation systems.

Modbus Communication Protocol Suite

Some Activities of the Modbus Organization are ...to Encourage, support and evolve ...

  • Participation in standards activities worldwide.
  • Leading the evolution of the Modbus protocol and its variants.
  • Modbus across a broad spectrum of physical layers and transmission media.
  • Conformance testing program to insure greater interoperability of Modbus devices.

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.

ASIC - Application-Specific Integrated Circuits

This resource about ASICs is the pages that went into the "ASICs... the book". When you get to Mass Production or want to pack a lot of electronics into a small size, an ASIC is inevitable. It improves reliability and consistency in the manufactured gadgets. It is a justified process, when a device is needed in large numbers. For smaller numbers use Flash Programmable Embedded Devices.

ASIC - Application-Specific Integrated Circuits

by Michael John Sebastian Smith - Addison-Wesley Publishing Company - VLSI Design Series

ASIC - Application-Specific Integrated Circuits

"ICs are made on a thin (a few hundred microns thick), circular silicon wafer , with each wafer holding hundreds of die (sometimes people use dies or dice for the plural of die). The transistors and wiring are made from many layers (usually between 10 and 15 distinct layers) built on top of one another. Each successive mask layer has a pattern that is defined using a mask similar to a glass photographic slide. The first half-dozen or so layers define the transistors. The last half-dozen or so layers define the metal wires between the transistors (the interconnect )."
