Fig. 96: ibaBM-DP/DP Monitor module in the S7-400H hardware configuration
A normal redundant slave (e. g. ET200) is shown with two connections in the hardware
configuration that are connected to both PROFIBUS systems. This redundant slave has
a single I/O address range (see figure above).
In contrast to that, an active slave of the ibaBM-DP has to be configured
on both bus
systems
. In both bus systems, the slave has to get the
same PROFIBUS address
.
This way, the configured slaves have each an own I/O address range. You can combine
the address range for each slave from the modules in the hardware catalog. A PROFI-
BUS slave can have a maximum payload data length of 244 bytes. This is why you
should use two modules of the “output 122 BYTES“ type.
Example configuration Step 7 hardware configuration
In the figure above, two active slaves have been configured (addresses 22 and 100).
The following address ranges have been assigned to:
Slave 22 – Bus 0
•
output 122 BYTES: 1024…1145
•
output 122 BYTES: 1146…1267
