OPC UA and Historical Data Access: How to Connect and Retrieve Data from Industrial Devices
OPC UA (Unified Architecture) and the OPC Historical Data Access (HDA) standard are powerful technologies that offer an all-encompassing solution for industrial data management. It is necessary to understand how to connect and retrieve data from industrial devices using these technologies to take advantage of their capabilities.
OPC UA requires the installation of an OPC UA server on the industrial device, which acts as a bridge between the device and the OPC UA client. The client can then connect to the server and request device data. OPC UA supports multiple communication protocols, including TCP/IP, serial, and Fieldbus. Once connected, the client has access to real-time data and can control the features of the device.
Installing an OPC HDA server, which acts as a bridge between the device and the OPC HDA client, is required for retrieving historical data from industrial devices utilizing OPC HDA. The client can then connect to the server and request historical device data. OPC HDA server will store data periodically or according to user-defined criteria, and the OPC HDA client can be used to retrieve and analyze the data.
It is also essential to note that OPC UA and OPC HDA are extensible, meaning they can be tailored to meet the specific needs of a given industrial automation project. For instance, custom data models and services can be created to add new functionality, and custom data storage and retrieval methods can be implemented to meet the project’s particular requirements.
Using OPC UA and OPC HDA to connect to and retrieve data from industrial devices entails installing servers on the devices, connecting to the servers, and requesting data. OPC UA enables access to and control over real-time data, while OPC HDA enables retrieval and storage of historical data for analysis and decision-making. Due to their extensibility and adaptability, OPC UA and OPC HDA can be adapted to meet the needs of any industrial automation project.
