PROFIBUS data transfer
6.5 Integration with the GSD file
Note
When selecting the slave "SENTRON WL/VL", only an MLFB number (e.g.
3WL9111-0AT15-0AA0) is displayed as information.
Note
The settings on the "Hex Parameterization" tab do not need to be considered here. The
PROFIBUS DP addresses 0 and 126 cannot be assigned. Address 0 is intended for the PG
(class 2 master) and 126 is used predominantly for startup purposes or is also frequently
used as the address of DP slaves as delivered.
Through integration with the GSD file, the SENTRON circuit breaker is always incorporated
as a DP standard slave. It is optionally possible to transfer additional data via DPV1 and, for
example, to change parameters.
Setting the input address/output address of the S7
After selecting the basic type, a SENTRON circuit breaker symbol is shown on PROFIBUS
DP. In the lower area of the split window, the input address/output address of the S7 which
can be accessed in the STEP7 program can/must be set.
