Abstract

The invention provides a method, a system and a computer readable storage medium for automatically configuring a process data object. The method includes judging whether a function of an auto-configuration process data object is opened, judging whether a current process data object is complete when the function of the auto-configuration process data object is judged to be opened, and configuring a new process data object when the current process data object is judged to be incomplete. The method of the invention can realize the automatic configuration of PDO, reduce the difficulty and time of manual configuration, reduce the probability of PDO deficiency and/or error caused by manual configuration, and improve the accuracy and reliability of PDO configuration.

Description

Method, system and computer readable storage medium for automatically configuring process data objects Technical Field The present invention relates generally to the field of process data objects, and more particularly to a method of automatically configuring a process data object, a system for automatically configuring a process data object, and a computer readable storage medium. Background A programmable logic controller (Programmable Logic Controller, PLC) is a control device commonly used in the field of industrial automation, and is widely used in various fields of industrial automation, such as a production line, a packaging machine, a conveying system, and the like. PLCopen functional blocks are an important component in the programming of the PLC for implementing specific functions, and are closely related to the control system of the PLC. In a motion control system, PLCopen function blocks are standardized function blocks for motion control, while process data objects (Progress Data Object, PDO) are objects for real-time data transmission. PLCopen blocks are associated with PDOs. The PLCopen functional block performs data transmission and communication through the PDO, and the PLCopen functional block realizes accurate motion control by assigning a value to the PDO, so that quick and accurate transmission of control instructions and feedback information is ensured. Because PDOs associated with the functional blocks are different, in some conventional schemes, the PDOs are manually configured by a person, and this configuration is not only inefficient, but also prone to missing and/or incorrect PDO configurations. When the PDO configuration is missing and/or wrong, the data of PLCopen functional blocks cannot be written into the servo driver normally, the PDO cannot be assigned accurately, accurate motion control cannot be realized, the missing and/or wrong PDO cannot be positioned, and the time and difficulty of manual debugging are increased. When the unnecessary PDO is configured, an additional communication burden is added. Thus, there is a need for an efficient and accurate PDO configuration scheme.
