6 most convenient methods to exchange data with Weintek HMI panel-0

Just imagine. You have the latest smartphone of 2023, but no SIM card. The cover and the screen are of course pretty. With the latest smart device, you can take beautiful photos and even surf through the settings menu, but communication options on the mobile network are as small as meeting a snowman in Mežapark. Similar parallels can be drawn with the HMI panel that performs data registration in the factory. There, the only way to view and analyze data is through the HMI visualization panel or screen. There is a lot of data, so further processing and analysis also takes time. You could say that just like communicating with a smartphone without a network - quite challenging.

Difficulties in data transfer and analysis

For the operator working on the machine, the data history is not relevant. Undeniably, it is worth gold in the eyes of quality control, planning and management. Accumulating data history is the easiest step in the whole equation. Most often, the greatest difficulties are caused by the transfer of the accumulated historical data for further processing and analysis. Several departments are most often involved in the further processing and analysis of data. Usually, also different specialists, each of whom has his own specific work platform and software. No doubt each of them has different requirements for receiving data. 

Six great methods for more convenient data exchange

In order to be able to fully provide data to the entire broad spectrum of users, one method of transferring history files will definitely not be enough. Thinking about user convenience and how flexible data exchange should be, Weintek HMI developers have approached this matter very seriously. The manufacturer offers a wide range of options for data storage and synchronization. Weintek HMI allows you to retrieve and synchronize historical data in several ways. In the following article, we will list 6 methods or ways to perform data accumulation and synchronization in the Weintek HMI visualization panel.

1. Save to USB memory

This is a classical method of data exchange. It allows you to get the history data directly by connecting the USB memory to the HMI panel and copying the data to it. Data can be saved in CSV or *.db data formats for further data processing and analysis.        

2. Send to e-mail

This method allows you to send history files to one or more e-mails automatically or on demand. This is usually in CSV or *.db data formats. Such data is obtained by several persons and the data relevant to them can be used

3. Download by connecting to the HMI web server EasyWeb.

This method allows you to get storm data in CSV and *.db formats. Downloading from the HMI web-server. In this way, anyone with an access password can access the history files. Data can be retrieved at any time. The best part is that there is no need to install specialized software to access the HMI panel

4. Synchronizing with the database

The Weintek HMI panel allows you to synchronize historical data with MySQL and MSSQL database systems. By the way, these are the two most popular systems in the world. With this method, data is stored in the database and updated independently. The database provides further data processing and analysis. In this way, we get a completely automated data processing and analysis solution.

5. Synchronizing with an FTP server

IUsing this method, Weintek HMI synchronizes the history data of the monitored process with the specified FTP server. Saving files in CSV or *.db formats. This method also allows you to create automatic data extraction from the FTP server and further processing.

6. Using OPC UA HDA

Weintek HMI can activate the OPC UA server and use the built-in function HDA (history data access). And in the OPC server of these functions, the history data of the selected variables is also stored. The data can be accessed using the OPC UA Client and further processed as needed.


It's impressive, isn't it? A total of 6 ways to get history data. Even more impressive is that you can use any of these methods and practically all of them simultaneously. With the Weintek HMI visualization panel, you will be able to successfully send data to different platforms, as well as to different users with other methods..
