Abstract

The embodiment of the invention provides an automatic program updating method and device. The method comprises the steps that an EtherCAT master station issues programs needing to be updated to all EtherCAT slave stations; the EtherCAT slave station receives the program which is issued by the EtherCAT master station and needs to be updated; and the EtherCAT slave station automatically updates theprogram which needs to be updated. According to the embodiment of the invention, hardware such as Ethernet, a USB and a serial port does not need to be added on the basis of slave station hardware, and automatic program updating is easy to realize; under the condition that automatic program updating fails, an original version program can be recovered; and the program can be automatically updated without manual intervention.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and device for automatically updating programs. Background technique [0002] At present, when the slave stations in the EtherCAT (Ethernet for Control Automation Technology, Ethernet control automation technology) network perform device updates, they mostly rely on manual updates or adding communication methods such as network interfaces, serial ports or USB on the slave stations. Download the program code to the corresponding slave device for update through these communication methods, or update the program through the corresponding debugging tool and development environment. [0003] However, the number of slave stations is increasing and the software versions of all devices need to be unified. The traditional method requires a lot of human resources to operate one by one, which obviously cannot meet the needs of automatic updates. [0004] Therefore, how to realiz...
