System integration
The following examples show different typical system integrations with ibaBM-DP.
8.1
Data acquisition 32Mbit Flex
Fig. 5: Configuration 32Mbit Flex – Sniffer function and/or active slaves
In the above example, the device is connected to 2 separate PROFIBUS lines. Using the
sniffer function the device can acquire all data sent on both PROFIBUS lines. In order to
use the sniffer function, the device does not need to be considered in the configuration
of the DP master.
Simultaneously, active slaves can be configured in the device, which then are supplied
with data in a targeted way. For this purpose, the device has to be entered via the GSD
file in the configuration of the DP master. The slaves (up to 8) can be optionally distrib-
uted on both DP lines.
ibaBM-DP is connected to the ibaPDA system via a bidirectional FO cable (ibaFOB-D
card). The configuration and the acquired data are exchanged via FO between ibaPDA
and ibaBM-DP.
8.1.1
Ring topology with 32Mbit Flex
Fig. 6:
Ring topology
In a ring with 32Mbit Flex protocol, up to 15 devices can be connected. All configuration
and measurement data are transmitted in the ring.
ibaPDA automatically detects the devices in the ring and determines automatically the
maximum possible sampling rate, depending on type and number of the devices.
In the ring, also other 32Mbit Flex capable iba devices can be integrated, e. g. ibaPADU-
S-CM like in the example above. The devices in the ring are addressed using the rotary
switch for the device address (rotary switch S2 for ibaBM-DP).
