Question: TIA Portal - WinCC OA Tag Management
Hello,
I am new to WinCC Open Architecture. I previously worked with WinCC Explorer, WinCC Unified, WinCC Professional, and WinCC Advanced, and OA feels like a completely different approach.
My question is about how to handle motor blocks in OA. In other SCADA systems, I used a function block for a motor, which was connected to a global DB based on a UDT (e.g., Motor_1, Motor_2, Motor_3, etc.). On the SCADA side, I worked directly with those global variables.
In OA, if I understand correctly, the approach is different: instead of using a global data block, you work with instance data blocks. Is that correct? Is this the intended way to structure things in OA?

If you are new to WinCC OA we recommend to get familiar with the basic concepts of WinCC OA.
You can do this by attending a WinCC OA Training or by using our eLearning platform.

Another option is to use the Getting Started Tutorial and the related WinCC OA project:

Information for the configuration of S7Plus and S7 driver and how to work with data from the TIA Portal you can find in the WinCC OA Documentation:
