OpenPLC version1 with LDmicro
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.
The Spoken Tutorials on OpenPLC will be based on OpenPLC Version 1 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.
LDmicro was available only for Windows initially. The FOSSEE team has ported it and made it available for Linux OS also.
OpenPLC version1 is based on 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.
The Spoken Tutorial effort for OpenPLC version1 with LDmicro has been contributed by Harsha Priyanka from FOSSEE team and Nirmala Venkat from Spoken Tutorials team.
The domain review is done by Akshay Chipkar and Rajesh Kushalkar from the FOSSEE team.
OpenPLC version 1 hardware schematic and gerber files for making PCB’s are available at links given below:

Students can perform OpenPLC experiments without OpenPLC hardware using the simulation mode in LDmicro. But we encourage having a hardware kit for better knowledge of the subject.
OpenPLC hardware kit consist of:
1. OpenPLC version1 Mainboard (1 no.) 2. 24V, 2A SMPS (1 no.) 3. USBasp programmer (1 no.) 4. Traffic Light module (1 no.) 5. Switchboard module (1 no.) 6. Heater module (1 no.) 7. Jumper wires 8. Relimate Connectors
