Does anybody know what's the maximum DPs in WinCC OA DB (not Oracle)?
There wouldn't be more than 1000 external DPs (periphery address configs)

Re: Theoratically maximum DP in DB
Hello,
as far as I know the theoratically technical limit for the number of datapoints is 2.147.483.648.
It is the same limit for the number of addresses (peripheral address configs).
In a real system this limit will never be reached because before reaching it the size of the project will be limiited by other factors (hardware)
How many addresses can be configured in your system is normally limited by the license you are using (keyword ios).
Using a project with 1000 IOs is normally not a problem, except if a low-performance hardware is used.
The hardware requirements for a WinCC OA system are described in the WinCC OA help. When using a computer with such a specification using 1000 IOs should not be a problem.
