Detailed Description
The present invention will be described in further detail with reference to the following examples in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the detailed description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the invention.
The principle of application of the invention is described in detail below with reference to the accompanying drawings.
As shown in fig. 1, the present invention provides a data redundancy editing method, which includes the following steps:
acquiring configuration information of a main plug-in unit and a redundant plug-in unit;
Creating a functional block capable of simultaneously reading the channel variable of the main plug-in unit-redundant plug-in unit on the visual page, inputting the tag value of the main plug-in unit variable by utilizing the functional block, and filling the tag value of the corresponding variable of the redundant plug-in unit according to a preset rule and configuration information of the main plug-in unit-redundant plug-in unit;
Compiling the visual page, downloading the product to a controller, when the controller runs on line, the output of the functional block preferentially takes the variable value of the main plug-in, and if the quality of the main plug-in variable returns an error mark, switching to take the variable value from the redundant plug-in and outputting.
Specifically, in the present invention, the hardware of the controller is managed according to the hierarchical structure of "station-branch-plug-in", and by setting the station number, the branch number, and the plug-in slot number, the plug-in position can be determined. And newly-building an insertion part on the right key of the branch node, and displaying the setting information of the redundant insertion part if the option of the main insertion part is checked in the newly-built dialog box popped up. The station number, branch number, and plug-in number of the redundant plug-in can be filled in. And simultaneously creating redundant plug-in nodes when the main plug-in nodes are newly built. And displaying the main plugin and the redundant plugin nodes under the hardware hierarchical tree nodes according to the hierarchical structures of the station numbers, the branch numbers and the plugin slot numbers.
As shown in fig. 2, clicking on the add-on node displays the add-on channel configuration interface. Each channel corresponds to 1 variable, plug-in variables are numbered from 1 according to hardware channel, and each channel variable uses KKS tags (20 characters conforming to the C language naming convention) as IDs.
The redundant plug-in is set to be in a read-only attribute, and the interface displayed by clicking the redundant plug-in is in a read-only state. When a certain channel variable of the main plug-in unit fills out or modifies the KKS label value, a message is sent to the redundant plug-in unit, and the KKS of the channel variable at the same position is the KKS+ "_R" suffix of the main plug-in unit. If other attributes of the variable (variable value, variable description, set value, unit, data type, alarm upper and lower limits) are modified, the attribute values of the redundant plug-ins are synchronized to be consistent with the primary plug-ins.
If the KKS is modified in batches through the replacement operation, when the variable KKS of the main plug-in unit accords with the replacement item and after the replacement, the KKS of the corresponding variable of the redundant plug-in unit is automatically set as the KKS+ "_R" suffix of the variable of the main plug-in unit. For example, replace apc_ai with APCAI, 1 KKS of the master plug-in is replaced by apc_ai01 with APCAI01, and KKS of the redundant plug-in has apc_ai01_r replaced by APCAI01_r.
The redundant plug-in right key conceals the delete menu. When the main plug-in is right-click to delete, the main plug-in records the corresponding redundant plug-in ID, so that the matched redundant plug-in can be triggered to be deleted. 1 controller supports creation of multiple pairs of master plug-ins-redundant plug-ins, which will check if there is a plug-in already set as a redundant plug-in at creation time.
Functional blocks for optional read main and redundant card channels have been developed, including analog reads REDHAI, integer reads REDHNI, and on-off reads REDHDI. As shown in fig. 3, a functional block capable of simultaneously reading the channel variable of the main plug-in and the redundant plug-in is created on the visual page, a symbol block is double-clicked, a label value apc_a01 of the main plug-in variable is input, a label value apc_a01_r of the corresponding variable of the redundant plug-in is automatically filled, and the information of the corresponding station number, the branch number, the slot number and the channel number of the main plug-in variable and the redundant plug-in variable are automatically filled. After the interface click is determined, a cross index symbol of IO and IO_R is formed on the left side of REDHAI symbols, and the symbol is double-clicked to jump to the plug-in configuration interface.
The foregoing has shown and described the basic principles and main features of the present invention and the advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
