How the AS-i cycle time depends on the number of connected slaves
The AS-i cycle time can be calculated using the following formula:
t
cycl
= (1 + number of activated AS-i slaves) x 154 ms
Note
If two AS-i slaves with extended addressing mode occupy the same address (for
example, address 5A and address 5B), this slave pair is calculated as one AS-i
slave in the above formula. The reason for this is that slave pairs with the same
address are addressed only in every second cycle. The cycle time in the formula
above is therefore doubled for such slaves.
