Hello, unfortunately I do not quite understand your questions; maybe it's a language thing. It would help if you formulate them somehow longer.

No, you do not have to use code from our examples. You are supposed to write your own code, with the help of the examples.

If the questions actually was whether you always need to do some coding to achieve what you want: Probably yes.

The "code-less" option you have mentioned (with Excel Option) might be possible, but only under very limited circumstances. The Excel Option does not require any coding, but is best at transferring values *from* the OPC server *to* Excel. There is a "trick" that allows it to also do writing (which is, in my understanding, what you want), but its capabilities are limited, and it would depend highly on your *precise* requirements whether that could be used for CSV loading (it was meant rather for actual user interface where the users enters a value and it gets written into the server afterwards). More about this feature is here: opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...ite%20with%20RTD%20Server.html .

Best regards

Yes, your understanding is correct. And QuickOPC can do it. It can be achieved in multiple ways. One of the easiest is to create a C# or VB.NET project in Visual Studio, write a code that reads the CSV lines and parses them for the values you need, and put in a code that does OPC "Write"-s to send the values to the PLC.

The very details of the code would slightly differ depending on whether you are dealing with OPC "Classic" Data Access server, or newer OPC Unified Architecture server. But in general, you would write the value similarly to examples that can be found here:

Let me know if this has helped, or what further questions you have.
