Problems solved by technology

[0005] In this way, the PLC needs to parse the XML file itself. Due to the limitation of the PLC performance, parsing the XML file is very resource-intensive for the embedded system of the PLC, which greatly increases the initialization time after the PLC configuration, which cannot be well satisfied. Some on-site environments with high performance requirements
On the other hand, the XML file has a complex structure and a large volume, which leads to slow transmission speed and also has a certain impact on the PLC initialization speed

Embodiment Construction

[0045] The initialization method of the PLC of the industrial server that the present invention proposes, by the binary file structure body (the binary file structure body is used to define each variable in the binary file location byte position) of the configuration file used by the upper computer according to the PLC to be initialized, Download the configuration data to generate a binary file to the PLC.

[0046] The binary file format that the present invention generates conforms to the definition of the binary file structure body of the configuration file of this PLC, therefore need not be the same as XML file, carry out file parsing again by PLC, PLC can directly put this binary file in memory, directly Operating and using the configuration data (referring to the configuration data in binary format) therein eliminates the process of parsing the XML file as in the background technology, and greatly reduces the time for PLC initialization. And because the binary file is sma...

Abstract

The invention provides a PLC initialization method of an industrial server. The PLC initialization method comprises the steps of: acquiring a binary file structure body of each configuration file defined by a PLC to be initialized; acquiring configuration data according to the configuration operation of a user on a configurable item corresponding to the configuration file, and generating a corresponding binary configuration file according to a binary file structure body of the configuration file; downloading the generated binary configuration files to the PLC in a binary data stream form; andputting the received binary data stream into a memory by the PLC, and initializing the PLC according to the configuration data in the memory. Correspondingly, the invention further provides a PLC initialization and readable storage medium. According to the invention, the initialization process after PLC configuration can be shortened.

Description

technical field [0001] The invention relates to the technical field of industrial automatic control, in particular to a PLC initialization method and device for an industrial server, and a computer-readable storage medium. Background technique [0002] With the continuous development of computer technology, signal processing technology, control technology network and the continuous improvement of user needs, programmable logic controller (PLC) has been widely used. Such as steel, petroleum, chemical industry, electric power, machinery manufacturing, express delivery and cultural entertainment and other industries. [0003] On the other hand, as a new technology, the technology of virtualizing a standard industrial computer into one or more PLCs with different functions through software technology is also developing rapidly. This technology is called soft PLC or virtual PLC (VPLC) technology. VPLC can realize the same functions as hard PLC, such as switch control, analog con...
