Abstract

The invention provides a method and a system for licensing software copyright of a PC soft controller, belonging to the field of industrial control. The method of the invention comprises the followingsteps: the PC soft controller software generates a series of random strings and sends them to an external module connected with the PC soft controller and provided with an authorization module; the PC soft controller software generates a series of random strings and sends them to an external module connected with the PC soft controller; after receiving the random string, the authorization modulegenerates copyright license information and sends it back to the PC soft controller software; the PC soft controller software judges whether the received copyright license information matches the copyright information generated by the PC soft controller software according to the random string, if yes, the PC soft controller software runs normally; if no, the PC soft controller software stops running. The invention has the advantages that the security of software copyright information can be improved, and the cost can be effectively reduced.

Description

technical field [0001] The invention relates to a software authorization method, in particular to a PC soft controller software copyright authorization method and system. Background technique [0002] Compared with embedded controllers, PCs have more powerful computing capabilities, but are limited by the weak real-time and stability of traditional Ethernet technology. Industrial control uses dedicated motion controllers or PC+ motion control cards. With the network The development of technology and fieldbus technology, especially the development of industrial Ethernet fieldbus technology such as EtherCAT, has greatly improved the real-time and stability of industrial control Ethernet communication. At this time, PC soft controller came into being. PC soft control The controller is a set of industrial control software running on a PC. It implements the functions of traditional controllers and control cards in the PC software, and transplants the EtherCAT master station proto...
