INTEGRATION OF PLC DRIVER WITH COMPUTER SYSTEMS

This article explores the integration of PLC (Programmable Logic Controller) drivers with computer systems, focusing on the possibilities and benefits of combining these technologies. By connecting PLCs to web-based systems such as ERP and MRP, users can monitor and control PLCs remotely from anywhere in the world. The paper discusses the technical implementation, such as creating sockets, sending and receiving XML messages for commands, and the overall advantages of having access to logs and real-time data influx for better operational efficiency.
