COMMUNICATION METHOD AND COMMUNICATION SYSTEM USED FOR THE COMMUNICATION METHOD

摘要

PURPOSE:To obtain a safe communication method with excellent error detection by forming a communication data of plural communication equipments connecting to one channel with a data part in succession to a common synchro nizing signal and a flag part representing defective communication. CONSTITUTION:A communication data 302 of plural communication equipments connecting to one communication line and applying mutual transmission/ reception consists of a data part 311 comprising the a communication destination and a communication content able to be distinguished together in succession to a common synchronizing signal 301 applying simultaneous transmission/ reception and a flag part 312 representing the presence of communication defect of each communication equipment. When there is no error in the data sent by its own communication equipment, a flag is set to the flag part 312 and the communication data is aborted when any communication error takes place in one communication equipment or over. Thus, discrimination and processing for data error causing noise or synchronization delay are applied properly and safe communication method with excellent error detection is obtained.
