(1540 Bytes). The data types BYTE, WORD, DWORD, INT, DINT, FLOAT and S5 FLOAT
in big/little endian format are supported.
When the device is operated in a ring topology with other 32Mbit Flex devices, the data
volume that can be transmitted, decreases accordingly.
Up to 8 slaves can be optionally assigned to bus 0/1.
With 32Mbit Flex, output signals of ibaPDA can be sent to the PROFIBUS master. Thus,
e. g. certain signal values can be monitored, a warning message is being issued in case
a limit value is exceeded or other events are signalized.
Note
ibaPDA processes output signals with lower priority compared to the acquisition of input
signals with a cycle not faster than 50 ms depending on the I/O configuration.
The redundancy mode can be used in 32Mbit Flex mode, see chapter 12. The use of
redundancy mode requires an additional license.
For further information, please see chapter 8.1, 8.3 and 10.1.
7.3.4.4 P2P mode
S1 = 4 and S2 = 0
With P2P mode (peer to peer), systems can be coupled bidirectionally to iba devices with
ibaNet 32Mbit interface via PROFIBUS (e.g. via ibaLink-VME to VME based control sys-
tems). For this purpose, the data from the ibaNet interface are mapped on up to 8 PRO-
FIBUS slaves: The data received by ibaBM-DP via fiber optic cable are output via the
input area of the PROFIBUS slaves. Data which are received over the output area of the
PROFIBUS slave, are output via fiber optic cables.
The P2P mode is applied in couplings of controllers with a ibaNet 32Mbit interface (e. g.
SIMATIC TDC with ibaLink VME) to new controllers via PROFIBUS, e.g. in moderniza-
tion projects.
For further information; please see chapters 8.5 and 8.9.2.
7.3.4.5 Simulation mode
S1 = 5 and S2 = 0
If you want to use the simulation mode, you need an additional license (order data see
chapter 2).
The simulation mode is designed to test the software and the configuration of a DP mas-
ter station, although the PROFIBUS environment is physically not available. Thus, e.g.
a new control program can be tested in a test environment and expensive downtimes
during the commissioning process can be reduced.
The PROFIBUS slaves that have been configured in the master, but are not physically
present, are simulated on the device. As the device analyzes the configuration telegrams
of the master, and generates from this information the required slave, you do not have
to configure the PROFIBUS in the ibaBM-DP.
Via a TCP/IP interface, the input values of the slaves are simulated and the output values
are requested. This TCP/IP interface for simulating the system can be used with any tool
(e.g. ibaLogic).
