Method for realizing axis information configuration of motion controller based on OPC-UA

Abstract

The invention discloses a method for realizing axis information configuration of a motion controller based on OPC-UA. The method comprises the following steps: module definition: defining input data processed by module functions as input parameters of a module and defining output data processed by the module functions as output parameters; process processing: detecting the legality of each of theinput parameters, returning an error status if the input parameter is wrong, ending modular configuration, starting to perform encapsulation processing on the module functions if the input data is legal, conveying the function module after the completion of encapsulation processing to an embedded platform for data loading and outputting module configuration completion results. The axis informationmodular configuration method has the benefits that a modular structure and the unified design architecture are adopted, and the module functions are correlated by using the input parameters and the output parameters; the functions of the required OPC-UA can be tailored according to the application demands, so that the execution efficiency is improved, and the application program customization requirements are met.

Description

technical field [0001] The invention relates to a modular configuration method, in particular to a method for realizing configuration of motion controller axis information based on OPC-UA. Background technique [0002] At present, most of the embedded motion controllers (Embedded Motion Control) use the OPC UA protocol based on the underlying development, and the integrated OPC UA Server adopts a solidified form, that is, the services and functions provided by the device have been planned in the early stage Once the product is formed or the project is completed, it cannot be modified in real time, which is not conducive to the secondary development and use of the product. Siemens S7 series PLC integrates the OPC UA Server service function. This device function is configured through the upper computer programming IDE to configure related parameters and is realized by using tabs. There are certain limitations in the realization of this function, and the secondary development c...
