Embodiment Construction

[0034] Such as figure 1 As shown, the configuration data of the control station of the present invention implements data sharing in a third-party database, which includes two tables in each relocation task, one of which is a table for the database, and another A table for the control station, which is a value-oriented data in the table of the control station; and the two tables are determined by the relocation task type to determine one as the source data table, another one Target data table, where the target data table is always populated by the data of the source data table, and the transformation of the data type of "source data table → target data table" is completed by the user's own mapping function.

[0035] Such as Figures 1 to 10C As shown, the present invention also provides a computer program product to implement the method of the present invention, the computer program product, which can be stored in a computer readable storage medium and includes a computer program in...

Abstract

The invention provides a method for realizing data sharing between the configuration data of the control station and the third-party database. The relocation task is used as the operation unit. Each relocation task includes two tables, one of which is a database-oriented table, and the other It is a control station-oriented table, and the data in the control station-oriented table is all numerical data; and the two tables are determined by the type of relocation task, one of which is the source data table, and the other is the target data Table, where the data of the target data table is always filled by the data of the data source table, and the conversion of the data type of "source data table → target data table" is completed by the mapping function compiled and generated by the user. The method of the invention realizes the data interaction between the upper layer application system and the bottom layer control by using the database as a transfer, and can realize the data interaction with heterogeneous systems.

Description

Technical field [0001] The present invention relates to the field of industrial control technology, and more particularly to a method of configuring data sharing in a configuration data of a control station and a third-party database. Background technique [0002] In the field of industrial control technology, there is currently no connection to the relational database in the IAP software architecture, so it is difficult to implement the control layer and the application management layer. Inventive content [0003] The technical problem to be solved by the present invention is to provide a method of configured data sharing of a control station and a third-party database to implement data interaction between the upper-layer application system and the underlying control in the database. The data interaction between the system system. [0004] The method of the present invention is achieved: a method of configuring data sharing in a control station, characterized in that the reloca...
