TitleMaking PLC (Programmable logic controller) by FPGA and

microcontroller

ByMojtaba Hajimiri

Ali nilechi

SupervisorDr. Siroos Toofan

PLC (Programmable logic controller) is one of the important parts in industry. So our purpose in this project were making a PLC. Towards this end, an electrical circuit is designed based on FPGA and other microcontrollers. Then, a PCB is designed using altium designer, and the functionality of the board is tested.

Our PLC in here contains 2 boards : 1- main board: this board consist of altera cyclone ii

EP2C8T144C8 FPGA and atmega128. we used this board as our main board. We writes the PLCs main program in quartus software (by graphical language-like FBD in PLC) on FPGA and then we sends our commands to atmega128 microcontroller that can be connected to our power board (by rs232 or ...).

2-power board: this board consists of atmega128 microcontroller as main processor and can been connected to our main board (by rs232 or ...). We used this board as our input-output board. this board consists of some protection circuits in his inputs that can be acquire different types of inputs. in this board we used relays to control automation systems.
