Abstract - This project indicates the design and development of programmable pi controller for automation using Raspberry Pi as the main processor to perform some specific operations. Arduino allows interfacing of both analog and digital signals hence it acts as controller for input and output module. Input module allows interfacing of sensors, switches, push button. Output module allows interfacing of different types of loads such as motors, indicators, alarms etc. Open PLC software is used for programming and this program is uploaded to raspberry pi via webserver through IP-address. This entire operation is supervised via SCADA using Modbus/TCP protocol with help of SCADA software called as SCADA LAQUIS. This is an alternative system for PLC as it reduces the cost of overall system used for automation and increases the flexibility and efficiency.
