Its not about theoretical value, but about real value in practice when controlling is still possible and acceptable.

Imediataly I download a program with more than 16 PID to "see what will happens", and it works. I don't remenber now how many PID I program at end, but I think that was 21. Without problem. At list while the presentation ran. This thema, remember me of the start of S7-300 whenwas in the catalog that the S7314 could just 16 PID run... PID isa subroutine, like any other. The limitstays principally insize of CPU memory, and runtime cycle.
