The principle of current PLC field programmability in industrial control system is studied deeply. The security models are set up respectively from the aspects of data confidentiality,integrity and identity authentication. The security mecha-nism of field programmability has been analyzed,and the three aspects are lack of necessary safety protection. The experiment platform was established,and the existed hidden trouble were verified by simulation experiment.
