使用 Python 读取 OPC HDA 服务器的数据吗?
原标题:Read data from OPC HDA server with Python?
I am aware that OPC HDA is an outdated protocol and shouldn t be used if there is any more modern protocol available. Sadly, in this industrial context, it seems there is no real alternative. I tried to find Python libraries with OPC HDA support without success. So I m asking here: Is it somehow possible to access data from OPC HDA with Python? If there is no way to directly read the data with Python, is there any workaround possible, like using a third-party tool as a bridge between OPC HDA and Python? The closest thing I could find are these OPC HDA loggers, which connect to an OPC HDA server, and log the data to flat files. That would probably somehow work, but I m wondering if there is any better solution. I m curious for your suggestions, thank you!

Best is probably to use an OPC HDA logger as you mentioned. This can be a bit cumbersome to set up, but it will work. You could try pyOPC. unknown how good that is.
I ve written a Jupyter Notebook to read HDA from ABB 800xA. Maybe it can help you. https://github.com/Tonny72/PyOpcHda
