A monitoring system and realization method of servo press based on network technology was explored, and the servo press monitoring system was programmed by C# language to establish a connection with the internal server of CODESYS controller through OPC UA communication technology. Then, the node data in the server was read and written, and the real-time monitoring of servo press processing parameters, real-time operating status data, IO signal and other operating status data was realized by subscription. Furthermore, the important operation data of press collected by the industrial gateway module was uploaded to the cloud management platform to realize the remote management and maintenance of press equipment, and through practical application verification, the system was simple to install, convenient to operate and stable to meet the needs of users. The results show that the research on this system has practical application significance in improving equipment intelligence, data visualization and networking.
