IECON 2018-44th Annual Conference of the IEEE Industrial Electronics Society
We have attempted to create affordable programmable logical controllers (PLC) that can be used to train millions of students in developing countries. Version 1 of the PLC is based on AtMega16 and costs 600 (10). Using the free and open source software (FOSS) LDMicro, one can learn ladder logic. To enhance the capabilities,using RaspberryPI,Version2ofthePLC,costing1,500(25) is made. We can use this device with the FOSS OpenPLC to learn ladder logic. We can also learn function block based programming using the FOSS 4DIAC. As ladder logic and function block based programming are industrial standards, students trained using our approach will be useful to industry.
