<P>PROBLEM TO BE SOLVED: To provide an access management method for input/output data using tag information that prevents an artificial setting error of a transmission address and a controller equipped with an input/output module mounted with an IC tag. <P>SOLUTION: In the access management method for input/output data by tag information, provided are a control controller 2 as a control station, an input/output module part 3 as a slave station, and a tag information processing part 6 which stores in an input/output transmission address table the tag information for identifying the input/output module and the transmission address of the input/output module corresponding to the tag information while making them correspond to each other, writes and reads the IC tag mounted on the input/output module, and reads out and transmits the transmission address of the input/output module used for the control controller 2, and the control controller 2 performs input/output access to the input/output module part 3 with the tag information and transmission address sent from the tag information processing part 6. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
