WL Circuit Breaker
Figure 3-1
You can use the STEP7 hardware configuration tool to configure the S7 automation system and its field buses. To add a circuit breaker, you
have to configure either a CPU with an integrated PROFIBUS-DP interface or a PROFIBUS-DP CP card in the rack and then assign it to the PROFIBUS-DP.
Figure 3-2
After you have dragged and dropped the SENTRON VL/WL from the
device library, the system displays this pop-up. You have to select the circuit breaker
basic type which the PLC uses to configure the circuit breaker.
Note:
You do not have to take the
settings on the “Hex parameterization”
tab page into account here. You
cannot assign the PROFIBUS-DP
addresses 0 and 126. Address 0 is for
the PG (class 2 master), while 126 is
mainly used for commissioning and
as the “as shipped” status of DP
slaves.
Integrating a WL circuit breaker using
the GSD file means that it is always
integrated as a standard DP slave.
You can, however, also transmit other
data and change parameters quickly
and easily via DPV1.
