Good morning at all, this is my first steps with WinCC OA..
I have a question about "dpconnect".
Can we abuse of dpconnect? :laugh:
If I create a custom "Field I/O" object, and associate it with a variable's output value, the best way is make a call with "dpconnect"?
Even if the objects in question become hundreds or thousands?
Is there a better way? :unsure:
Thanks you a lot!

Re: Best way to create thousands of i/o fields with a lot of dpconnect
When your new to WinCC OA then i'd suggest that you go to the lab section first. There are some X-File documents (that i wrote years ago) that can help you.
First read number 9 which gives you an overview and then read number 1 (that will show you how a dpConnect works)
First realise how the WinCC OA Event manager works before you start making 1000's of connect.
yes, even a good car can crash against a tree.
WinCC OA is a powerfull tool. Use it wisely

Yeah, I think you're right!
I'm veteran of Wincc 6 / 7.X, which is definitely different from WinCC OA ..
I just wanted to start with the right mindset, to understand the best approach! I still have the tag-oriented mindset.
I have already done a course in etm, watched several tutorials, and read the documentation in question (which I still have to keep up).
Currently we continue to develop with Wincc 7.4, and in parallel we are moving to OA, only with small steps.
So even by creating a small object for the tests (in fact, in this case we talk about an i/o field) I want to start with the mentality of having to apply it to many variables
