Test the significance of security controls
    Security control experiment is the basic condition for the experiment. Is to ensure personal safety and security of the basic equipment requirements.
Production accidents
Ø laboratory personnel for a long time of work overload, resulting in fatigue, decreased attention.
Ø laboratory personnel due to lack of effective training, resulting in the misuse of equipment.
Ø do not follow the correct operating procedures.
Ø  device does not use safety equipment or failure during operation.
Main technical characteristics:
Ø the relevant security controls integrated into the IO sub-module system
Ø have the same modular system with standard features
Ø  independent of the lower field bus system
Ø comply with IEC 61508, EN 954, ISO13849 and other safety standards
Ø  Use open communication protocol
