Standard mapping 3-4:
Module
0 Input - 16 Bytes
1 Input - 16 Bytes
2 Input - 14 Bytes
3 Input - 16 Words, consistent
4 Output - 14 Bytes
Addr_Ix and Addr_Ox indicate arbitrary (as a rule even) addresses in the I/O address-
ing range of the PROFIBUS DP master.
Addr_Ix (base address of the inputs) is identical with offset 0 of the PROFIBUS DP
message data of the SIPROTEC device in input direction (ref. to chap. 3.2, 4.2 and
5.2).
Addr_Ox (base address of the outputs) is identical with offset 0 of the PROFIBUS DP
message data of the SIPROTEC device in output direction (ref. to chap. 3.1, 4.1 and
5.1).
