7.4 Device-specific Profibus DP parameters
With up to 100 bytes of the device-specific Profibus parameters the addresses of the analogue input
slaves and analogue output slaves to be transferred in parallel can be defined and the parameters of
the connected AS-i slaves can be set.

Legend
MM 2 bits Master no. 1…2
X 1 bit Slave type 0 = single or A slave
1 = B slave

Calculation of the more significant byte (MMXSSSSS):
(slave no.) + (master no. * 64
dec
) + (32
dec
, if B slave)
Examples:
Master 1 Slave 3(A) 1*64 + 3 = 67
dec
= 43
hex
Master 2 Slave 5(A) 2*64 + 5 = 133
dec
= 85
