Problems solved by technology
Since the Modbus TCP protocol communicates in a question-and-answer manner, the communication takes a certain amount of time. When there are many commands, the communication time will be superimposed and there will be a considerable delay.
And this kind of delay is reflected in motion control as motion freeze, which obviously cannot meet the requirements

The invention discloses an industrial motion control system and an industrial motion control method based on an API. The industrial motion control system comprises an industrial PC control subsystem and a PLC control subsystem. The industrial PC control subsystem comprises a control module and an API database. The PLC control subsystem comprises a PLC motion controller and a plurality of servo drivers. The control module is used to generate motion control instructions, and is used to process feedback data from the PLC control subsystem. The API database is used to cache the motion control instructions from the control module, and is used to transmit the motion control instructions to the PLC control subsystem once, and is used to read the feedback data of the PLC control subsystem, which is provided for the industrial PC control subsystem. The PLC motion controller is used to control a plurality of servo drivers according to the motion control instructions, and is used to generate the feedback data. A plurality of servo drivers are used to control the corresponding motor motion under the control of the PLC motion controller. Communication data redundancy is greatly reduced, and objects of accelerating communication speed and satisfying system requirements are achieved.
Description
technical field [0001] The present invention relates to the technical field of automation control, in particular to an API (Application Programming Interface, Application Programming Interface)-based industrial motion control system and method. Background technique [0002] At present, in the field of industrial motion control, there are mainly two control methods: one is realized through a motion control card; the other is realized through a PLC (Programmable Logic Controller, programmable logic controller). [0003] In the way realized by the motion control card, the control card is inserted on the host PC (Personal Computer, personal computer) through the PCI (Peripheral Component Interconnect, peripheral component interconnection standard) slot; using advanced programming languages C++, C#, VB, VB.NET, LabVIEW and other programming languages are used for development; the control card API interface function provided by the motion control card manufacturer is used in p...
