COMMUNICATION NETWORK AND ITS INFORMATION CONTROL METHOD

摘要

PURPOSE:To know the contents of a program control table and a task execution control table at the client side by providing a network controller to file the control information. CONSTITUTION:When a user program is locally corrected, the user program is corrected via a local terminal of an FA equipment 10 and the corrected program is down-loaded into a user program storage part 11. At the same time, a program control table 33 and a task execution control table 34 are corrected via a maintenance operation control terminal of a MAP i/F unit 30. Then the contents of both tables 33 and 34 are up-loaded into a network controller 60 as a system domain 61. Thus a general client 50 can acquire the correction information with an inquiry given to the controller 60 despite the local change of the user program of the equipment 10.
