The data of the device and the connected AS-i systems to be transferred can be defined (by indicating
the length of up to 12 modules) in the programming software for the Profibus DP master system (host).
You can select from these definitions for parameter setting in the host:
Profibus modules; example for module 1:
There is a choice of 5 entries:
all single and A slaves on AS-i master 1
(length = 16 bytes)
single and A slaves with the addresses
1(A)...23(A) on AS-i master 1
(length = 12 bytes)
single and A slaves with the addresses
1(A)...15(A) on AS-i master 1
(length = 8 bytes)
single and A slaves with the addresses
1(A)...7(A) on AS-i master 1
(length = 4 bytes)
no single or A slaves on AS-i master 1
(length = 0 byte)
If the parameters for a smaller number of slaves than indicated in the selection point are to be set, you
have created free reserve in the host.
Example:
5 single and/or A slaves are connected to the AS-i master 1.
You have selected on the host:
"single and A slaves with the addresses 1(A)...7(A) on AS-i master 1"
You have then created an address area reserve of 1 byte in the host which is not used for the time being. The first 3 bytes of the
reserved address area are used to exchange data.
