Slave Mode

In the industrial control system, the communication framework of the master-slave mode is usually set up according to the general requirement of the control system. This paper mainly introduces the design and implementation of the PLC master-slave mode control system, using the MPI communication mode to realize data transmission between the master station and slave station, so as to realize the requirement of control system.

Adequate Data

Most of the communication protocols in the Industrial Control System (ICS) are vulnerable to cyber-attacks. Initially, the network protocol was designed for reliable performance, and thus did not incorporate data transmission security features. Therefore, ICS requires adequate data transmission security. This paper suggests improving the security of data transmission through a dynamic symmetric four-key-generators system, wherein the system anticipates cyberattacks by generating four keys before encryption. It involves four generators: a random initial key generator, a keystream generator, a key scheduling algorithm generator, and a pseudo-random number algorithm generator. In the receiver section, the system generates three keys before decryption to ensure data confidentiality and to avoid cyberattacks. The test results show that the proposed system keyspace is ≈22048 bits, meaning that the key is more secure from brute force attacks. As a result, the cipher data have a correlation value of 0.00007. The entropy value is 7.99, indicating that the cipher data is more secure. Also, speed tests show that the processing time still qualifies as realtime.

Further Development

A progress report on the architectural design and implementation of the Control System for the Racetrack Microtron at the Institute of Accelerating Systems and Applications (IASA) in Athens, Greece is presented. The Control System for the IASA CW Microtron is being developed on the Experimental Physics and Industrial Control System (EPICS) environment. Since top priority for this project is the construction and commissioning of the Mcrotron's injector, emphasis is being given to the definition and refinement of the Control Architecture and its realization for the injector. The experience gained from the Control System at the injector will guide the further development of the Control System for the entire Microtron.
