Abstract: A maintenance support system includes a numerical controller that controls the drive of an operating mechanism of an industrial machine and a server that is a support device capable of communicating with the numerical controller, and the maintenance support system supports maintenance of the industrial machine. The numerical controller includes a first information generating unit that acquires, from among data related to a state of operation of the operating mechanism, data related to the state of operation of the operating mechanism when an anomaly is found in an operation of the operating mechanism, and generates first information including the data acquired. The server includes a second information generating unit that generates second information to be proposed to the numerical controller for the maintenance on the basis of the content of the first information.

Abstract: A management server (200) has a storage section to store a program set (110) and a user management table. The management server receives user information from a development computer (300), authenticates a user on the basis of the received user information and user information included in the user management table, and transmits the program set to the development computer. The development computer edits a source program included in the program set, registers user information in the program set, and transmits the program set to the management server. The management server receives the program set, updates the program set stored in the storage section with the received program set, and updates the user information included in the user management table with the user information included in the received program set.

Abstract: A control system which protects a control program securely and improves a convenience for a particular user in reading and writing an execution-use control program from and into a PLC. The control system includes: a controller which controls a production apparatus; a development-use computer which converts a control program that describes control of the production apparatus, into the execution-use control program that can be executed by the controller, and encrypts the execution-use control program converted, thus generating an edit-use key for editing and an execution-use key for execution; and a management server which manages information on the user. The development-use computer registers the edit-use key in a user management table of the management server, and transmits the execution-use key and the execution-use control program to the controller.
