PROBLEM TO BE SOLVED: To provide a bus communication method that quickly safely transmits and receives data between a plurality of communication apparatuses connected to the same bus. SOLUTION: A safety control task 3 in each of safety control stations SCS1, SCS2, ..., SCS64 performs operation by using the operation data of a necessary area out of received link transmission data according to an implemented safety logic. Further, the safety control task writes the link transmission data to its own area when necessary, and then performs the broadcast transmission of the link transmission data through a link transmission part 1.
