Problems solved by technology

[0006] In the related art, during the process of flashing or downloading the application program of the controller, the control parameters can only be assigned one by one and the state of the control parameters cannot be monitored, resulting in low efficiency, low accuracy and poor security of the system updating control parameters. No effective solution has been proposed yet, for this reason, the main purpose of the present invention is to provide a method and device for processing control parameters in a controller to solve the above problems

Embodiment 1

[0019] Before describing further details of various embodiments of the invention, reference will be made to figure 1 A suitable computing architecture that can be used to implement the principles of the invention is described. In the following description, unless indicated otherwise, embodiments of the invention are described with reference to acts and symbolic representations of operations that are performed by one or more computers. It will thus be appreciated that such acts and operations, which are sometimes referred to as computer-implemented, include the manipulation of electrical signals representing data in a structured form by the processing unit of a computer. This manipulation transforms the data or maintains it at a location in the computer's memory system, which reconfigures or changes the operation of the computer in a manner well understood by those skilled in the art. A data structure that maintains data is a physical location in memory that has specific prope...

Embodiment 2

[0064] figure 2 is a schematic flowchart of a method for processing control parameters in a controller according to an embodiment of the present invention; image 3 It is a detailed flow diagram of an optional embodiment of a method for processing control parameters in a controller according to the present invention; Figure 4 It is a detailed flowchart of another optional embodiment of the method for processing control parameters in the controller according to the present invention.

[0065] Such as figure 2 As shown, the method may include the following steps:

[0066] Step S10, by figure 1 The loading module 20 shown loads the application program when the system is powered on and starts running.

[0067] Step S30, by figure 1 The detection module 40 is shown to detect whether the flag bit of the control parameter group in the storage area is the same as the predetermined value in the application program, wherein the predetermined value is a fixed value.

Abstract

The invention discloses a method and device for processing control parameters in a controller. The method includes the steps of loading an application program when a system is powered on and operates; detecting whether the zone bit of a control parameter set in a storage region is the same as a predetermined value of the application program or not; assigning default initial values of the control parameters to corresponding control parameters in the control parameter set under the circumstance that the zone bit is not the same as the predetermined value and assigning the zone bit as the predetermined value; carrying out consistency verification on the control parameter set under the condition that the zone bit is the same as the predetermined value and determining control parameters subjected to abnormal updating in the control parameter set. According to the method and device, automatic bulk assignment conducted on the control parameters can be achieved, abnormal updating of the control parameters is monitored, and therefore security of the system is also improved on the basis that updating efficiency and accuracy of the control parameters are improved, and operation troubles of the system caused by the abnormal updating of the control parameters are avoided.

Description

technical field [0001] The invention relates to the field of automation control, in particular to a method and device for processing control parameters in a controller. Background technique [0002] The invention relates to the field of automation controllers, and mainly aims at a method for automatically assigning initial values ​​to control parameters and accumulating and summing the consistency of stored parameters and checking and troubleshooting for engineering machinery PLC controllers. [0003] When the existing PLC controller flashes and downloads the application program compiled by the user, the initial default value of the control parameters required for the operation calculation of the application program usually cannot be downloaded to the PLC controller together with the application program. , using the method of manual writing, assign default initial values ​​to each control parameter one by one, so that the application program can operate with the initial defa...
