 So, we have a project that is open source PLC. So, you all might be knowing what is PLC. So, the PLC is a special type of computer that is usually being used in industrial applications. The open source PLC is microcontroller based PLC which can be programmed using open source software like LD micro and Baltic programming. So, we are using right now is LD micro. The objective of this project is to develop a hardware setup for the PLC. So, we have already designed few experiments for this open source PLC. We are using Arduino Uno as a programmer board and we have performed around seven experiments using Arduino Uno and we are going to build a virtual lab for this open source PLC to make it accessible remotely from various places by students or anyone who is interested to work on PLCs. And one more objective is to teach this ladder programming in polytechnics and ITI colleges where actually in many of the polytechnic and ITI colleges there is PLC which is taught only theoretically not practically. So, we are going to build a low cost hardware setup for that so that it can be taught in those colleges. These are MDHC programming for programming the hardware setup and Arduino programming and interfacing various sensors and various basic objects with Arduino Uno and that is all and the next project is sila solution.
