Title: OPCDAcom (Timestamp and Quality)
Post by: erduarte on January 17, 2018, 07:03:06 AM

Good Morning! I´m using OPC to read data from OPC tunnel software. I can read data values from my tags. How can i read timestamp and quality from these tags? It is possible?

Regards

Ed

Not with the OpcDaCom driver. This driver is merely a wrapper that simplifies access to an OPC server by stripping everything except the value.

If you want more information, then you will need to write the code to directly access the OPC server. You can Google "OPC .net" and find some code examples like this:
