Due to the large data amounts that are usually captured with ibaBM-DP, it makes sense
in most cases to operate just one device on a 32Mbit Flex link.
Reserved bandwidth for Ethernet communication
The Ethernet channel (address 0) is used to transmit configuration data, to communicate
with the web interface and especially with ibaBM-DP for the display of the Profibus diag-
nosis. If many devices are configured with a lot of signals, it may happen, that only the
minimum size of 1 kB/s is reserved for Ethernet communication. This is not sufficient in
many cases and may cause, that the Profibus diagnosis cannot be displayed or the com-
munication with the web interface is very slow.
It is now possible to reserve a fixed bandwidth for the Ethernet channel with the option
„Reserve bandwidth for ethernet communication“. The default value of 4 kB/s is usually
sufficient for configuration data and Profibus diagnosis.
