jfDataLogger ============ jfDataLogger can log data from PLC controllers. Supports Hardware: - Siemens S7-300/400 PLCs - AllenBradley (CompactLogic Controllers only) - ModBus IP protocol - National Instruments DAQmx System Features: - Trigger bit at start - Save/Load data set - Save Image - log to CSV Website: http://jfdatalogger.sourceforge.net

Framework to enable PLC Visualisations (like Wago 750-841, Beck IPC, CoDeSys 2.3) displayed in a standalone Browser without Java applets. Including Browsers of iPad, iPhone, iPod, Android aso.. Based on HTML5 canvas and Javascript.

CoDeSys v2.3 supports so called network variables. Blocks of (global) variables, that propagates over networks like TCP, UDP or UDP Multicast aso. This python module supports parsing, receiving and sending those blocks (with UDP Multicast only). With this you can add for example a Raspberry Pi Sensor to your automation network without special Network clients on your PLC.

PLC-EMU is a Programmable Logic Controller EMUlator for automation applications on linux with digital/analog IO cards, with C functions, Ladder Diagrams,or IEC61131-compliant Instruction List/Structured Text. It is a cheap and open alternative to PLCs.

Modbus TCP, Modbus UDP and Modbus RTU client/server library and Simulators for JAVA Suitable for data exchange between JAVA-Applications and PLCs like Schneider-electric; Siemens S7; Wago; Bosch-Rexroth; CoDeSys Devices and many more. Supports Function Codes: - Read Coils (FC1) - Read Discrete Inputs (FC2) - Read Holding Registers (FC3) - Read Input Registers (FC4) - Write Single Coil (FC5) - Write Single Register (FC6) - Write Multiple Coils (FC15) - Write Multiple Registers (FC16) - Read/Write Multiple Registers (FC23) See http://www.easymodbustcp.net for implementation guide and codesamples javadoc: http://easymodbustcp.net/javadoc/javadoc/index.html V2.7: Bugfixes and Methods to send/receive String V2.6: Timeout Modbus RTU V2.5: Bugfixes and Modbus RTU Impementation for Client Packaged has been changed; that means that this version is imcompatible with previous versions. ...

Libnodave is a library that provides the necessary functions to connect to and exchange data with Siemens S7 300/400 PLCs (200 family and S5 family now also supported). Can now also be used under Win32.

A command line tool to query Modbus TCP hosts. At this stage, the client allows read holding registers only. Useful to read data registers from PLCs or any Modbus TCP compatible equipment.

AUTOMGEN runtime is an open source royalty free runtime for open PLCs. By using this runtime, any target systems can become compatible with the AUTOMGEN automation workshop: IEC1131 languages (ladder, SFC, etc.), 2D and 3D scada, WEB SCADA, etc.

A Library to exchange data with GE Fanuc PLCs over ethernet.

An OPC-XML compliant server for the MODBUS protocol used in process controllers and PLCs. It will provide low-cost access to plant data and support futher development of Open SCADA applications. Based on the OpenDA (opc-xml) project.

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, but still used in many old PLCs installations.
