More Information
Summary:The invention discloses a data consistency method and device based on multiple IEC tasks and a computer storable medium, is applied to a controller, and comprises the steps that a configuration project downloaded into the controller through downloading operation is received; wherein the configuration project comprises a plurality of IEC tasks; mapping all data of each IEC task to a continuous physical address area; data of different IEC tasks are mapped to different continuous physical address areas; the continuous physical address area is an area of a non-addressable part of a user data area of the controller. According to the method, the device and the computer readable storage medium, the consistency of private data can be realized when a plurality of IEC tasks are executed in parallel, and the multi-task running efficiency is improved. 本申请公开了一种基于多个IEC任务的数据一致性方法、装置及计算机可存储介质，应用于控制器，包括：接收通过下装操作下载到控制器中的组态工程；其中，所述组态工程包括多个IEC任务；将每个IEC任务的全部数据整体映射到连续物理地址区域；不同的IEC任务的数据映射到不同的连续物理地址区域；所述连续物理地址区域为所述控制器的用户数据区的不可寻址部分的区
