Method and system for solving occupation of Ethernet network port

Abstract

The invention relates to the technical field of communication, and discloses a method for preventing an Ethernet network port from being occupied, which comprises the following steps of: developing a machine PLC (Programmable Logic Controller) using an Ethernet module, and configuring the Ethernet network port; newly adding a communication message format; developing related code data of the equipment module control module according to the communication message format, and newly adding configuration of multiple groups of Ethernet network ports in the equipment module control module according to the related code data; developing related code data of the detection control module according to the communication message format, and newly adding time configuration in the development of the detection control module according to the related code data; alarm configuration is added to the detection control module, and alarm processing logic of the detection control module is added to form a total processing rule for solving the problem that the Ethernet network port is occupied. The invention further discloses a system for solving the problem that the Ethernet network port is occupied. The method is used for the situation that the connection is accidentally disconnected due to unknown reasons when data acquisition is carried out through the Ethernet module in a factory.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, a method and system for solving the problem of Ethernet network port being occupied, which is used for sporadic unexplained disconnection during data collection through the Ethernet module on the production machine in an automated factory In the case of connection, it is used when the TCP / IP port is occupied, and in the case of real-time data acquisition and real-time data interaction between the production control program and the equipment. Background technique [0002] As the degree of automation and digitalization of factories continues to increase, the production data of products is becoming more and more important, and many systems for analyzing production have emerged as the times require. The data collection of these analysis systems is generally collected by the production control program or data collection system through the PLC of the machine. Some of thes...

Problems solved by technology

[0004] 1. After the traditional processing method, the port will be occupied after the communication is interrupted, and it cannot be reconnected

[0005] 2. The current processing method has a great impact on production activities. The traditional restart of the PLC operation can solve this problem, but the PLC cannot restart the operation during the production process. It can only be restarted after the completion of the production activities. Then the data during this period is basically just can't collect

[0006] 3. Abnormal occurrences are extremely accidental, and may not occur during long-term operation, or may occur multiple times in a short period of time, so operators cannot always pay attention to the status of communication and data collection in real time

[0007] 4. Traditional processing methods are all manual operations, and risks are prone to occur when improper operation

[0008] 5. When the real-time process data cannot be reported for a long time, due to the lack of data support, abnormal process data cannot be detected, which may affect the production process and cause defective products

[0009] Therefore, in order to solve the above problems, a technical method is urgently needed, which can solve the problem that the communication cannot be established due to the network port being occupied after the network is interrupted due to unknown reasons.
