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.

Spinwave Systems’ Wireless Thermostat Controller is a drop-in replacement for almost any existing conventional non-communicating thermostat, re-using the existing equipment wiring. Thermostat functions and values are accessible remotely through an embedded web page of the Modbus Mesh Gateway or via Modbus communication.



Wireless Thermostat Controller, SWC-TSTAT-1

The wireless thermostat controller is a full function wireless mesh device with integrated radio that can be configured to control heat pump systems, (with auxiliary or emergency heating if necessary), gas/oil heating systems with add on cooling, control high and low balance points as well as the number of heating and cooling stages needing precise control. It can even adapt to manage the number of fan speeds it must control.

Bluetooth Multimeter - Seeed Studio

"Bluetooth Multimeter is an intelligent peripheral of android phones, specially designed for engineers. Not only can it easily collect data such as voltage, current and resistance etc., this multimeter can also communicate with phones via bluetooth. Thus, the data gathered will be displayed on your phones."

Bluetooth Multimeter - Seeed Studio

Totally open source, including hardware, software & Android API. Learn how to create a Platform to connect smartphones with the real life.

Bluetooth Multimeter - Seeed Studio

The Bluetooth Multimeter is based on Atmega328 - Arduino Pro. It measures the voltage and resistance and current input from the headphone jack, and then sent these data via the Bluetooth frame.

Android UI for Bluetooth DMM

This Bluetooth Multimeter is a portable multimeter, a device that gathers the voltage, resistance and current. and then sent these data to other device via Bluetooth, so, we could display the data through other devices, such as Android, PC and so on.

USB PIC a easy PC Interface

PIC18F4550 has a USB Interface easy to use, code or configure. This page will help in trying out this PC friendly PIC Microcontroller.

The CREATE USB Interface

The Create USB Interface is an open source microcontroller board that can be programmed in C, BASIC, or Arduino languages. This latest version is called the CUI32Stem, which is designed to work ‘hand-in-hand’ with the GROVE prototyping system including a wide range of sensors and actuators.

USB PIC a easy PC Interface

PIC18F4550

The PIC is the heart of the board. It's a programmable microcontroller with 32Kbytes of flash program memory and 2kbytes of general purpose SRAM. It has 13 A/D inputs and 18 general purpose I/O ports. On the CUI board, one of the general purpose I/O pins is dedicated to the "program" button to enter bootloading mode. You can use the remaining ports for anything you wish.
