INDUSTRIAL CONTROLLER AND DATA SHARING METHOD IN INDUSTRIAL CONTROLLER

摘要

The present invention addresses the problem of providing a program development assistance system in an industrial controller that is capable of improving development efficiency without needing manual allocation operations, and a data sharing method in the system. A cooperative file generation unit (212) of a control program development PC (101) generates a map file (210) and a header file (209) by extracting a variable name of a control program (207). In an information program development PC (102), an information program (219) is generated by a user using the generated header file (209). In an industrial controller (103), the information program (219) causes a shared access unit (220) to access a shared storage region (224) by using the map file (210), to access data by using a shared variable.
