Abstract

The invention discloses a remote system for PLC equipment debugging and a method thereof. The system consists of virtual serial port bridging software, a background server and an industrial gateway concentrator, wherein the industrial gateway concentrator equipment on a physical connection line is connected with traditional PLC equipment; the virtual serial port bridging software is connected withIDE software of a corresponding PLC through a virtual serial port; a transmission layer protocol central server is connected with the virtual serial port bridging software through an HTTP protocol and connected with the industrial gateway concentrator equipment through an MQTT protocol; the industrial gateway concentrator equipment is connected with the PLC through the physical connection line and sends information in a transparent transmission line; and the virtual serial port bridging software sends information in the same transparent transmission line. According to the system and the method, the users do not need to change the original programs and can remotely debug the PLC equipment without being limited by territories, so that the operation is convenient and efficient.

Description

technical field [0001] The invention relates to network communication and serial port communication, in particular to a remote system and method for debugging PLC equipment based on network communication technology. Background technique [0002] Regarding the PLC remote debugging technology, the commonly used method in the prior art is the PLC debugging through the telephone line, which is slow and expensive. Or through the router to build a virtual private network for PLC debugging, the module is complex and subject to conditions. The traditional method has the following disadvantages: [0003] First, environmental and geographical restrictions. Wiring is difficult for some products, and the traditional method needs to introduce telephone lines or Ethernet lines for network communication, which is not suitable for this part of products; [0004] Second, the data stability is poor. Some products can only transmit data, and cannot maintain and resend data packet loss and ...
