Modbus is one of important protocol in industrial application but does not have any security parameters to protect the information which is carried by Modbus protocol. For which we have to develop intrusion prevention systems(IPS) to avoid active and passive attacks. For this study we have to design a hardware model on which Modbus protocol is implemented and physical standard used is RS-485. So we have developed following circuit of which one will acting as a master node and second as sensor node. Hardware section is divided into two parts namely master node and sensor node between which RS-485 is used as a physical medium between two above nodes on which Modbus protocol is implemented. Both master and sensor nodes are discussed below
