Problems solved by technology

However, the existing data interaction is through setting up a public data area, and different types of controllers will directly read and write to the public data area. Since the written data is not verified, repeated reading and writing by the same type of controllers will occur. Loss of data, possibly resulting in logical exceptions

Embodiment Construction

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0047] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intervening element at the same time. When an element is referred to as being "disposed on" another element, it can be directly disposed on the other element or intervening elements may also be present.

[0048] Unless otherwise defined, all technical and scientific terms used here...

Abstract

A data interaction method, the first control device is used to read and write data from a storage device, the storage device includes a data identification area, a data area and a check area, the data identification area is used for storing data identification, and the data area is used for To store data, the check area is used to store check codes. The method includes the following steps: the first control device reads the data identifier from the data identifier area; the first control device judges whether the data identifier is a write-in identifier; when the data identifier is the write-in identifier, the first A control device writes data into the data area; and when the data mark is the write mark, the first control device writes a new check code into the check area and modifies the data mark as the first read mark . The invention also relates to a data interaction system and memory. The above data interaction method, system and memory can ensure the security of the interactive data and prevent the data from being changed accidentally when it is not read.

Description

technical field [0001] The invention relates to a data interaction method, system and memory. Background technique [0002] In smart factories, different types of controllers such as servers and programmable logic controllers (PLCs) are used to automate the control of the workshop production line system. Data interaction between these controllers is required to achieve coordination and synchronization. However, the existing data interaction is through setting up a public data area, and different types of controllers will directly read and write to the public data area. Since the written data is not verified, repeated reading and writing by the same type of controllers will occur. Data is lost, possibly resulting in logical exceptions. Contents of the invention [0003] In view of the above situation, it is necessary to provide a secure data interaction method, system and storage. [0004] A data interaction method, the first control device is used to read and write data...
