Short Version:
We must connect 150+ PLC devices from multiple OPC-related systems to extract data. Is there an interim solution that seamlessly integrates with existing setups to supply our databases?
hey dude, sometimes simply linking your db to an opc ua server and using its builtin data adapter works well. i unt relied on heavy middleware, so testing an integrated opc solution might cut extra layers and risks.
Based on similar challenges I’ve encountered, deploying a dedicated middleware or OPC UA gateway can serve as a viable interim solution. This approach involves establishing a centralized service that communicates with all 150+ PLC devices while converting and routing data to the target databases. It is beneficial as it minimizes disruption and leverages existing infrastructure. My experience shows that such middleware facilitates data homogenization and provides a manageable layer for error handling and performance monitoring, ensuring the solution remains scalable as system requirements evolve.
hey, i think a small dedicated opc gateway might work incase of high traffic. i tested a custom lightweight adapter in sim tests, but did u folks face any hiccups with such setups? how did it mesh with legacy systems?
Drawing from practical experience, implementing a dedicated OPC UA integration layer that device-proxies data between the PLC devices and your databases has proven to be both reliable and scalable. In a previous system, we built an intermediary service which not only managed the communication to over a hundred devices but also performed real-time data normalization and error filtering. This configuration minimized integration risks by centralizing the processing of data while retaining compatibility with the existing infrastructure, thereby providing a solid interim solution for large-scale data extraction.
