It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
According to the interactive data storage/acquisition method/system, the readable storage medium and the terminal, data storage can be separately stored on a plurality of plc controllers for storage redundancy to ensure the validity and safety of data, so that a server can perform data storage on specific data by initializing and configuring the plc controllers, and then simply access a database from the plc terminal to acquire data display.
Example one
The embodiment provides an interactive storage method of data, which is applied to a communication network comprising a plurality of controllers and a server side in communication connection with the controllers; the interactive storage method of the data comprises the following steps:
after the controller is started, judging whether network setting of the communication network from the server side is received or not; if so, searching the controller associated with the network according to the network setting, and establishing communication connection with the controller associated with the network setting so as to interactively store data with the associated controller; if not, continuing the next step;
and sequentially searching the controllers adjacent to the controllers, and establishing communication connection with the adjacent controllers so as to interactively store data with the adjacent controllers.
The following describes the interactive storage method of data provided by the present embodiment in detail with reference to the drawings. The method for storing data interactively according to this embodiment is applied to a communication network 1 as shown in fig. 1, where the communication network 1 includes a plurality of controllers 11 and a server 12 communicatively connected to the plurality of controllers 11.

In this embodiment, the network settings of the communication network include the number of controllers in the communication network, the network topology of the communication network, and/or the IP address of each controller.
S22, if the network setting of the communication network is received, the controller associated with the network setting is searched according to the network setting.
And S24, establishing a communication connection with the controller associated therewith so as to interactively store data with the associated controller.
For example, a plurality of plc controllers are directly searched from the local ip and connected to each other on the lan, and the connection is stopped when a certain number of plc controllers are reached, so that the plc controllers can access each other in an intersecting manner, each plc controller can obtain the data of other plc controllers, and in normal operation, the plc controllers exchange specified stored data with each other to form a multiple data backup by the settings on the tablet computer or the server, and when the server or the platform reads data, upload all the data cached on the local computer at one time, and if the server or the platform obtains the data of the corresponding other plc controllers, it is not necessary to read the corresponding data from the other plc controllers.
S23, if the network setting of the communication network is not received, the controllers adjacent to the communication network are sequentially searched.
For example, 3 plc controllers, controller a, controller B, and controller C, are connected to a tablet computer or a server, respectively, and the three plc controllers scan the controllers adjacent to the IP sequentially without any network setup.
And S25, establishing a communication connection with the adjacent controller so as to interactively store data with the adjacent controller.
Specifically, according to the own IP address, the controllers adjacent to the own IP address are sequentially searched, and communication connection is established with the controllers adjacent to the own IP address.
For example, controller a is connected to controller C and controller B is connected to controller a. The controller A simultaneously stores data of the local computer and the controller C, the controller B simultaneously stores data of the local computer and the controller A, the controller C simultaneously stores data of the local computer and the controller B, the panel simultaneously obtains the data of the A and the data of the C when accessing the controller A during scanning, and then accesses the B to obtain the data of the B and the data of the A because the data of the controller C is obtained in the period, the data are not required to be obtained from the C, and the mutual saved relation and the number can be set by the panel to manually interfere with the backup topological state.
And S26, after receiving the access request from the server, feeding back the data stored by the server and the data of the controller interacting with the server to the server.

and continuing to access the data on the controller which does not interact with the controller to be accessed in the last step, and acquiring the data on the controller.

Please refer to fig. 2B, which is a flowchart illustrating an exemplary data acquisition method. As shown in fig. 2B, the data obtaining method specifically includes the following steps:

In this embodiment, after receiving the access request, the controller to be accessed feeds back data stored by itself and data of the controller interacting with the controller to store the data to the server.
For example, when the tablet computer accesses the controller a, the data of the controller a and the controller C which interactively stores the data with the controller a are simultaneously obtained, and then the access controller B obtains the data of the controller B and the controller a which interactively stores the data with the controller B.
S22 ', data on the controller that did not interact with the controller to be accessed in S21' is continuously accessed, and the data stored on the controller is retrieved.
For example, controller D does not interactively store data with controller A and controller B, and continues to access controller D to obtain the data stored on controller D.
