Does everyone know the authorization methods and point calculation methods for various DCs and PLCs?
Each one is different; some calculate the number of hardware channels, some calculate them separately for different types of IO, and some also take into account the number of communication points. . . . .
General-purpose software is relatively simple, especially the upper-level software. Programs like Ifix and Wincc support configurations with 64, 128, and so on input/output points; it seems the same is true for domestic products as well. However, the calculation involved in DCS systems appears to be quite complex, as it involves accounting for IO channels, display screens, and more
The most complicated aspect is the LICENSE for the DELTAV system; it comes in DI, DO, AI, AO variants, and there’s also the PROFESSIONAL PLUS STATION version, with a maximum value of 30,000 DST
For ABB’s 800xA, the calculation is done for each individual point in terms of hardware, and it also needs to be calculated on the control screen
WINCC: It is available in 512, 1024, 32k, 64k, and 256k versions, but this includes all external and internal variables；
But 256,000 – is there really such a high level of hierarchy? I guess for a system of that scale, it would be better to use DCS
