MUTUAL ACCESS METHOD OF DATA AND MUTUAL ACCESS SYSTEM OF DATA

摘要

A variable is defined by one engineering device. A tag name is assigned to the variable that the other device accesses, and a corresponding table of the tag name and the variable name is created. Further, a tag object is converted to a tag list in a format that can be interpreted by the other device, and the tag list is downloaded to the other device. The tag name of the access from the other device is converted to the variable name with reference to the corresponding table.
