PROBLEM TO BE SOLVED: To perform data conversion by selecting only a piece of data to which the data conversion is required irrespective of difference between the endians of master/slave information equipment that perform data communication. SOLUTION: A CPU 28 of a master 10 refers to a data table 30 in which endian information of a slave 12 as a data transfer destination is preliminarily stored and raises a flag only when the data conversion is not required. In a data converter that has received data 24, a decision device 34 sorts the data according to presence/absence of the flag and records the sorted data in an address space 40 or 42. Software 46 read by a CPU 50 of the data converter performs the data conversion to only the data recorded in the address space 40, defines it as converted data 26 and transfers it to the slave 12. |
