At the beginning the maximun number of slaves in ANY ASI network was 32, but with the new ASI profiles there are A and B slaves, so then you can have 32x2=64.
Saying that you can have 64 slaves is not 100% true, since there are slave modules that use A&B as analog input/outputs or 8DI modules; and then the maximum number is reduced.
It´s more accurate to say that you can have 32A slaves and 32B slaves, and when any module uses the A and B slave number it uses 2 slaves.
