Addressing
An unambiguous PROFIsafe target address ensures that a data telegram reaches the
correct node.
The valid address within the range between 1 and 1023 can be set via the DIP switch .The
address 0 is invalid and causes an error in the module.
DIP switch Labelling
1 2 3 4 5 6 7 8 9 0
Value of the address bit 1 2 4 8 16 32 64 128 256 512
Note!
The combination ”safety module SM300 from version VA 1.08 and
communication module PROFIBUS from version VB 0.93” offers the
opportunity to avoid the error that occurs when an address i s set to 0. For this
purpose, a defined PROFIsafe target address must be saved in
C13897 or 14897 in the PROFIBUS communication module.
