Note: QuickOPC now supports Python in much better way, cleaner syntax, and public packages (pypi.org/project/opclabs-quickopc/) on Python Package Index . See What's new in QuickOPC 2023.2 for more information. And, over 270 examples are available in the User's Guide!

At this moment I cannot verify whether that works, but it should look something like this:

client.WriteItemValue('', 'OPCLabs.KitServer.2', 'Simulation.Register_I4', 12345)
Best regards

Hello,

I would like to know how to perfom a writing operation through python at OPC DA. I saw the reading sample and it works.

Can you please send me a example like the one below?


# Perform the operation
value = client.ReadItemValue('', 'OPCLabs.KitServer.2', 'Demo.Single'))
