You can also set the communication parameters using the BDA, as well as the
parameters for operation on the Ethernet/intranet/Internet.

You can also use STEP7 to change the PROFIBUS address. To do so, however, the PC
with STEP7 must be connected to the slave by means of an MPI or PROFIBUS interface.
Setting the PROFIBUS Address for
the COM15 Module
The PROFIBUS-DP address is stored
in the COM15 PROFIBUS-DP module
on the circuit breaker. The system is
shipped with the default address 126.
All the stations on the PROFIBUS-DP
must have a unique address, which
means that a new address must be
assigned when the PROFIBUS-DP
modules are commissioned.
The COM15 module adopts the new
address, although it cannot be used
until the 24V DC supply voltage for
the
Cubicle
BUS
has been interrupted
briefly. The address is not active until
the voltage is restored.
