Problems solved by technology

[0003] With the development of society, higher requirements are put forward for PLC. Traditional PLC monitoring can only monitor data by writing data into the database of the host computer. If the host computer is not connected or due to network problems The data cannot be stored in time, and when the PLC runs in error, it is impossible to analyze the cause of the error and the operating state before the error occurred. Therefore, a method and system for implementing data storage monitoring applied to PLC configuration is invented to solve the above problems

Embodiment 1

[0043] A method for implementing data storage monitoring applied to PLC configuration, the steps of the method are as follows:

[0044] S1 Add storage module and management module in PLC configuration;

[0045] The S2 management module judges the connection status between the PLC configuration and the host computer;

[0046] When S3 is not connected, the management module stores the running status and data of the PLC configuration in the storage module;

[0047] When S4 is connected, the management module stores the running status and data of the PLC configuration in the host computer database;

[0048] The purpose of the inventive method is to carry out certain storage to data and can record log information in corresponding position, when PLC operation error, can read data information and log information before error occurs in the corresponding chip by connecting host computer, for Restore the running state before the error and provide corresponding data and status; firstly...

Embodiment 2

[0065] An implementation system for data storage monitoring applied to PLC configuration, the system specifically includes a function setting module, a signal connection module, a first data transfer module and a second data transfer module:

[0066] Function setting module: add storage module and management module in PLC configuration;

[0067] Signal connection module: the management module judges the connection status between the PLC configuration and the host computer;

[0068] The first data transfer module: when not connected, the management module stores the running status and data of the PLC configuration in the storage module;

[0069] The second data transfer module: when connected, the management module stores the running status and data of the PLC configuration in the host computer database;

[0070] The purpose of the system of the present invention is to store the data to a certain extent and can record log information at the corresponding position. When the PLC...

Abstract

The invention discloses a method and system for realizing data storage monitoring applied to PLC configuration, and belongs to the field of embedded controllers. The method specifically comprises thefollowing steps that S1, a storage module and a management module are added in PLC configuration; S2, the management module judges the connection state of the PLC configuration and an upper computer;S3, when the PLC configuration is not connected, the management module stores the running state and data of the PLC configuration in the storage module; and S4, during connection, the management module stores the running state and data of the PLC configuration in an upper computer database. By adding the management module and the storage module, a prompt function is corrected in time when data recording and operation errors occur, so that normal operation of PLC configuration during application is ensured, and a clearer processing scheme is provided for wrong data and reasons when PLC configuration operation errors occur.

Description

technical field [0001] The invention discloses a method and system for realizing data storage monitoring applied to PLC configuration, and relates to the technical field of embedded controllers. Background technique [0002] The abbreviation of PLC—Programmable Logic Controller (Programmable Logic Controller) widely used in automation technology. It has the characteristics of high reliability, low power consumption, and simple structure, and overcomes a series of problems caused by complicated wiring in traditional control systems. For a long time, PLC has always been the protagonist of industrial automation, and has formed a tripartite confrontation with DCS machine IPC. At the same time, PLC is also under the impact of other technical products. Miniaturization, networking, IPC, and openness are the main directions for the future development of PLC. [0003] With the development of society, higher requirements are put forward for PLC. Traditional PLC monitoring can only m...
