P2P mode

P2P mode
Using the P2P (peer to peer) mode, systems can be coupled bidirectionally to iba devices
with ibaNet 32Mbit interface via PROFIBUS (e.g. via ibaLink-VME to VME-based control
systems). For this purpose, data from the ibaNet interface are mapped on up to 8 PRO-
FIBUS slaves that can be arbitrarily distributed over the two DP lines: 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 slaves, are output via
fiber optic cables. The slaves have to be defined via the GSD file in the configuration of
the PROFIBUS master.
The P2P mode is applied in couplings of controllers with an ibaNet 32Mbit interface (e. g.
SIMATIC TDC with ibaLink-VME) to new controllers via PROFIBUS, e. g. in moderniza-
tion projects.
Configuration of the slaves and the data mapping is done exclusively in the web dialog
of ibaBM-DP (see chapter 9.3.4.2).
Note
In P2P mode, the ibaBM-DP device is operated without ibaPDA. It is only used to couple
the 32Mbit ibaNet interface and the PROFIBUS slaves. You cannot record data in par-
allel via ibaPDA.
