Industrial control system security is crucial to economic development, social stability, and national security. In recent years, with the deepening integration of informatization and industrialization, industrial control systems have evolved from stand-alone systems to interconnected systems, from closed systems to open systems, and from automation to intelligence. While productivity has significantly increased, industrial control systems face increasingly severe information security threats.
Statistics show that there were approximately 1,700 work-related accidents nationwide in January 2017, resulting in over 1,100 injuries and fatalities. While domestic companies are increasingly emphasizing equipment safety, accidents continue to occur frequently. Why is this? The main reason lies in numerous misconceptions regarding safety precautions...
Many people believe that a PLC with high stability and high performance can replace the role of a safety controller. This is a misconception. Often, despite investing a lot, they still cannot get real safety.
Safety controller function
The dual CPUs of the safety controller can execute the same user program once on each side, and then compare the two results. If the comparison results match, the result is output; otherwise, the safe result is selected for output.
Simply put, it has a "self-test". For example, if your safety switch has been used for too long and has aged, causing the output signal to be incorrect, the safety controller can detect it in time and stop the equipment to ensure the safety of the operator.
