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.
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).
I will give a simple example for the purpose of understanding and assimilation of the concept. Consider the Toaster a Vital Home Appliance, Build a Embedded Internet Interface into the toaster. Then make it Wireless Networking capable. The gadget can also get connected thru Mains Carrier Communication.
Now you build a Webware service, create API’s, Ready Gadgets and Wizards. So he can create-use the API from any Computer or PDA. He can Sub-Lease his custom API Service with Internet capable Gadgets.
Make this a Web Toaster – When i made this post, the iGoogle was the reason behind it.
Digital Timer for Internet – Live Widget
But Then, the service should be easy for just anyone to use, the coding is never done by the user of the service. He creates an account, hires the API, creates his own Gadgets and Apps with wizards. Then he gets to download the firmware for the Embedded Internet ASIC you Provide and the Product he manufactures goes with that circuit. See a Screenshot below
The end customer buys an Internet capable Toaster with a CD demo on how to access his free webservice. With this service, he can get all the web gadgets and tools to control his Home Appliance Arsenal.
