2 Introduction
The PROFINET bus monitor ibaBM-PN is a device for acquiring the cyclical data ex-
change between the PROFINET (PN) controller and PN devices. The device supports
PROFINET IO specification V2.35 and can be integrated in an existing PROFINET net-
work with one or more standard PN controllers.
The bus monitor has 2 independent, internal PN devices, which can be supplied with
data by PN controllers. A bus monitor can communicate with several PN controllers. For
this purpose, the device has to be integrated in a PN engineering project. The bus mon-
itor can be integrated in line or star topologies and can be connected as well to two
independent PROFINET lines.
The two PN devices each support S2 system redundancy independently of each other.
An additional license is required for this.
To act as sniffer, ibaBM-PN can be integrated into the PROFINET network without inter-
ferences using the TAP-interface (Ethernet). As a sniffer, the device monitors the data
exchange between PN controller and PN devices.
The entire communication via the TAP-interface is being mirrored to a monitor port and
can be recorded using an external network analysis tool.
On the optical-fiber side, ibaBM-PN works with the ibaNet protocol 32Mbit Flex. With this
protocol, measuring and configuration data are transferred via a bidirectional fiber optic
connection. The sampling rate and the data formats can be configured flexibly.
The both internal PN devices of the bus monitor can be configured independently in
ibaPDA. Each of the internal PN devices can capture up to 1440 bytes (incl. status bytes)
per cycle.
Furthermore, ibaBM-PN provides the function to acquire and record data as sniffer on a
SINAMICS Link and thus replaces the bus monitor ibaBM-SiLink in a functionally com-
patible way. SINAMICS Link is a special type of PROFINET communication for exchang-
ing PROFINET IRT data between Siemens SINAMICS controllers. SINAMICS Link is
based on a strict, straight network topology with a maximum of 64 PROFINET (PN) con-
trollers.
Each controller sends data that ibaBM-PN can read and acquire. The sampling time can
be decreased down to 500 µs when less controllers are connected.
Overview of the most important characteristic values:
2 independent internal PROFINET IO devices
Each PN device has a 2-port switch
Up to 4 controllers can be connected per device (shared device)
Up to 1440 bytes per device

7.3 Operating elements, connections
7.3.1 FO connections X10 (TX) and X11 (RX)
X11 (RX): FO receiving interface
X10 (TX): FO sending interface
On the ibaPDA system, a FO input/output card of the ibaFOB-D or ibaFOB-Dexp type
has to be installed for receiving and sending the data.
Maximum distance of fiber optic connections
The maximum distance of fiber optic connections between 2 devices depends on various
influencing factors. This includes, for example, the specification of the fiber (e.g.
62.5/125 μm, 50/125 μm, etc.), or the attenuation of other components in the fiber optic
cable plant such as couplers or patch panels.
However, the maximum distance can be estimated on the basis of the output power of
the transmitting interface (TX) or the sensitivity of the receiving interface (RX). A model
calculation can be found in chapter 11.4.
The specification of the transmitter's output power and the receiver's sensitivity of the
fiber optic components installed in the device can be found in chapter "Technical data"
11.1 under "ibaNet interface".
7.3.2 Voltage supply X14
The ibaBM-PN device has to be operated with an external DC voltage 24 V (unregulat-
ed) with a maximum current consumption of 400 mA. The operating voltage should be
supplied using the 2-pin Phoenix screw connector included in delivery.
7.3.3 Push button S10
With the S10 push button, all settings can be reset to the factory settings:
1. Switch off the device.
2. Switch on the device with the push button S10 keeping pushed.
3. Keep the push button S10 pushed until the green LED "Run" of the operating status
display starts blinking rapidly. Now, release the push button.
4. When the green LED "Run" stops blinking rapidly, the factory settings have been
applied. The device is immediately ready for operation and does not need to be
switched off and on again.
Note
The device must not be switched off during this procedure.

Each of the two PROFINET devices X40 and X41 has an independent 2-port switch with
RJ45 (10/ 100Mbit/s) connectors. The two switches are not internally connected.
When the autonegotiation is switched off, the P2R port of each device functions as uplink
port, i.e. you do not need a cross-cable for connecting another device.
7.3.6 TAP interface X42
With the TAP interface, the device can be integrated in an Ethernet/PROFINET network
without any interferences. The whole data exchange can be acquired.
7.3.7 Service interface X12
The Ethernet interface „X12 Service“ (RJ45) at the bottom of the device is designated
for service purposes.
The Ethernet interface is set to a static IP address 192.168.1.1 which cannot be changed.
7.3.8 Monitor interface X13
The Ethernet interface „X13 Monitor“ (RJ45, 1Gbit/s, no autonegotiation) at the bottom
of the device is designated for connecting a network analysis tool like e.g. Wireshark1.
The communication via the TAP interface is mirrored and output on the X13 Monitor
interface.
7.3.9 Shield connector X29
Connector (screw) for connecting the protective ground. Depending on the configuration
of the control cabinet, it might be necessary to connect the shields of the PROFINET
cable to the shield connector X29. Use a M6 terminal for connecting purposes.
If the shields of the PROFINET cables have been connected yet to the protective ground
of the control cabinet, also connect the shield connector X29 to the protective ground of
the control cabinet.

8.4 Data acquisition with TAP / Sniffer
Figure 7: Data acqusition with TAP / Sniffer
In the above example, the TAP interface is used for aquiring and analyzing the trans-
ferred data without interferences. It does not have to be integrated into the configuration
of the PROFINET controller.
The installation location within the PROFINET line is relevant. The TAP interface always
has to be integrated linearly. You can only acquire data which are transmitted at this
position in the network.
8.5 Media Redundancy Protocol (MRP)
The Media Redundancy Protocol is a PROFINET feature and allows you to build up a
ring-topology network. Using redundant physical connections, a higher reliability of the
PROFINET network can be reached.
Both PROFINET device interfaces support MRP as a MRP client as well as MRPD-client.
Via the TAP interface, data can also be acquired in a ring topology, as long as the con-
nection telegrams can be recorded. Depending on the configuration status of the MRP
ring (sending direction in the ring), the dataflow of the PROFINET telegrams changes.
Also depending on the installation location of the ibaBM-PN only those data can be ac-
quired which are currently transported at this position of the network.
Important Note
ibaBM
-PN in sniffer operation is not designed to be used in a MRP ring topology.

Figure 8: Data acquisition with 2 devices and TAP/Sniffer
With the example above, we show one possible scenario how to combine the different
versions.
Here, we show the data acquisition via TAP/Sniffer and both PROFINET devices.
The installation location within the PROFINET line is relevant regarding the TAP inter-
face. The TAP interface always has to be integrated linearly. You can only acquire data
which are transmitted at this position in the network.
8.7 Data acquisition at SINAMICS Link
SINAMICS Link is a special type of PROFINET communication for exchanging
PROFINET IRT data between Siemens SINAMICS controllers. SINAMICS Link is based
on a strict, straight network topology with a maximum of 64 PROFINET (PN) controllers.
Note
SINAMICS Link allows data exchange between the Control Units CU320-2PN and
CU320-2DP. For this purpose they must be equipped with the CBE20 option board.
