Other AbstractThe invention relates to the field of automatic control and technologies of large-scale programmable logic controllers and specifically provides a safety parameter sequence protective module of large-scale PLC and a method. The module and the method provided by the invention are characterized in that a parameter sequence route collection module, a parameter sequence route assessment module, an orthogonal parameter sequence route set module, an indefinite parameter sequence route set module, a non-orthogonal parameter sequence route set module, a parameter sequence checking generator, a parameter sequence route protective module and a dynamic parameter sequence route set module are added on an original hardware platform of the large-scale PLC. According to the invention, additional hardware circuits are not needed for realization of the method, wherein a high processing capacity of the large-scale PLC can be used for processing. The module and the method have the advantages that reliability of the large-scale PLC can be increased, and the PLC can be monitored on line all the time during running.
