PROBLEM TO BE SOLVED: To provide a safety logic module system, used in a safety network disposed in a process plant. SOLUTION: The process plant includes a process controller connected to a process control input/output device for performing a process control function, and a safety logic solver connected to a safety field device to communicate through a first communication bus, and the safety logic module system includes a computer readable memory storing in the safety logic module. When the safety logic module is performed by the processor of the safety logic solver, a safety function is performed for one or multiple safety field devices to communicate with another safety logic module in another safety logic solver connected to the first communication bus through a second communication bus, and the process controller and the process control input/output device are communicated with each other through the first communication bus.
