SnapModbus is an Open-Source multi-platform suite (library and tools) to manage Modbus communication in strict adherence to the modbus.org specifications, both master and slave side. It supports all the functions described in the documents: * MODBUS APPLICATION PROTOCOL SPECIFICATION V1.1b3 * MODBUS MESSAGING ON TCP/IP IMPLEMENTATION GUIDE V1.0b * MODBUS over Serial Line - Specification and Implementation Guide V1.02 through the standard transport protocols and the most widespread unofficial protocols (UDP, RTU Over TCP, RTU Over UDP) It’s released under lglp v3, so it’s free also for commercial use.

The Simple components for Ada library provides implementations of smart pointers for automatically collected objects (using reference counting), object persistence, unbounded and bounded arrays of smart pointers, generic unbounded arrays of private objects and plain pointers, generic sets, maps, arbitrary precision arithmetic, B-trees, directed graphs, directed weighted graphs, stacks, and storage pools. It also includes table management, string editing, IEEE 754 support, and infix...

A class to manage Modbus frames and another to make a Modbus server. Both classes are fully portable. An example of a modbus server is given. The code is very simple and comprehensive. Note ; Qt includes some classes related to Modbus since Qt 5.6.

We are developing a set of Delphi components to communicate with a ModBus PLC over TCP/IP. The library provides components to implement both a ModBus master and a Modbus slave, and is based on the Indy component set (both Indy 9 and 10 are supported) De source code of the project has been moved to GitHub!

Java modbus slave scanner - NetBeans 6.5 project

QSCADA will be an open source SCADA application generator for Linux O.S. The IDE will allow to visually design the application and will generate the code for the server and client parts. Modbus for Linux and Qt library will be used.

PROJECT HAS MOVED HERE: https://github.com/Elektordi/x-way-uni-te X-Way and UNI-TE (also used in Unitelway) are communication protocols for old Schneider Electrics PLCs (Programmable Logic Controllers), formerly "Modicon Télémécanique". The aim of this open-source project is to create a Java library to send and receive such data, because there is actually no open-source project at all in this field. Keep in mind that those protocols are old and not maintained anymore by any company,...
