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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control system for securely protecting a control program when editing, executing and transmitting the control program","description":"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.
