Industrial training has become an essential part in training personnel and getting them ready for the challenging work in the industry. An Open Source Hardware initiative by FOSSEE Project at IIT Bombay presents OpenPLC, an open source Programmable Logic Controller. This Cost effective, robust, dynamic and modular hardware with open source software enables students from various streams of Engineering and Polytechnics to learn Industrial automation using Ladder Logic programming language, one of the widely used languages in automation industries. Spoken Tutorials on OpenPLC will be based on OpenPLC hardware and LDmicro software. Both are available free and open source to use. LDmicro generates native code for microcontrollers like Atmel AVR and Microchip PIC16. OpenPLC is based on the ATMega16 AVR microcontroller. The board is equipped with sets of digital and analog input/output pins, a standard ISP header to which you can connect an external programmer for loading programs from computers, output power pins, external UART module, reset button etc and input power terminal.
