The Siemens S7 protocol is commonly used in SCADA systems for communications between a Human Machine Interface (HMI) and the Programmable Logic Controllers (PLCs). This paper presents a model-based Intrusion Detection Systems (IDS) designed for S7 networks. The approach is based on the key observation that S7 traffic to and from a specific PLC is highly periodic; as a result, each HMI-PLC chann...

A kind of fuzzy-PID controller with adjustable factor is designed in this paper. Scale factor’s selfadjust will come true. Fuzzy control algorithm is finished in STEP7 software, and then downloaded in S7300 PLC. WinCC software will be used to control the change-trend in real time. Data communication between S7-300 PLC and WinCC is achieved by MPI. The research shows that this fuzzy-PID controll...
