2 Introduction
The device ibaBM-eCAT can be used for reading and recording of data transmitted over
an EtherCAT®bus with ibaPDA. For this purpose, the ibaBM-eCAT device is directly
integrated into the bus after the EtherCAT master.
Diagnostics and monitoring of the EtherCAT bus is also possible using the diagnostic
signals integrated in the device and the EtherCAT browser.
The settings for the device as well as the configuration of the data to be acquired are
performed in the I/O manager of the program ibaPDA. For this purpose a bidirectional
fiber optic connection to a PC is required, which is provided by a fiber optic card of the
ibaFOB-D familiy (e. g. ibaFOB-io-D).
The signal configuration can be retrieved from the EtherCAT configuration of the Ether-
CAT master. An export function in the EtherCAT master is required to generate a config-
uration file in XML format. This EtherCAT configuration file is imported into ibaPDA, al-
lowing the signals to be selected comfortably in the symbol browser of ibaPDA with a
mouse click.
If no EtherCAT configuration file is available, the values for the acquisition can be se-
lected directly from the EtherCAT bus using an EtherCAT browser.
The EtherCAT browser also provides diagnostic functions for the bus. For example, the
individual telegrams can be analyzed and the cycle and turnaround time can be dis-
played. A large number of diagnostic signals describing the EtherCAT bus are available
to be acquired in ibaPDA.
In addition, ibaBM-eCAT can be integrated as a slave into the EtherCAT bus configura-
tion and can then be addressed specifically by the EtherCAT master. In this way, user
data can be sent directly from the EtherCAT master to the bus for being recorded in
ibaPDA. Those signals are regarded as outputs from the EtherCAT bus’ view.
The following signal configurations are possible:
512 analog signals in each direction (input and output)
The data formats BYTE, SINT, WORD, INT, DWORD, DINT, REAL, FLOAT and
LREAL are supported.
512 digital signals in each direction (input and output).
Note when using as EtherCAT slave
The maximum number of analog and digital signals is limited to 512 each (outputs),
whereby the LREAL data format (64 bit) has to be count as 2 analog signals.
The overall data volume of the analog and the digital channels 0-7 is limited to
1360 Bytes.
The overall data volume of the analog and the digital channels 8-15 is limited to
1360 Bytes.
These restrictions mentioned above apply only, when the MTU (maximum transmission
unit) size is set to the maximum value of 1514 Bytes.

8 System integration
8.1 Integration into the EtherCAT bus
The ibaBM-eCAT device is integrated into the EtherCAT bus directly after the EtherCAT
master. The device provides 2 EtherCAT interfaces, which are galvanically isolated from
each other. The EtherCAT interface X40 is connected to the EtherCAT master, the Ether-
CAT interface X41 to the first slave.
In this configuration, 512 analog and 512 digital signals can be captured in each direc-
tion. If more signals are required, several ibaBM-eCAT devices can be integrated into
the EtherCAT bus directly after the master.
Figure 3: Topology (EtherCAT master and EtherCAT slave)
When
ibaBM-
eCAT is switched off, the EtherCAT connection between the master and the
slaves will be interrupted!
Note
If it is not possible to integrate the device between the EtherCAT master and the first
slave, it can also be integrated elsewhere in the bus or even at the end. However, not all
I/O data of the bus can be
acquired.
ibaBM
-eCAT can only be operated at the bus end if it has been configured as an Ether-
CAT slave and the option
"Single/last device" has been enabled.

8.2 Integration as single EtherCAT device
The ibaBM-eCAT device is the only device connected to another EtherCAT interface of
the master system.
The X40 EtherCAT connection is connected to the EtherCAT master, the X41 EtherCAT
connection remains disconnected.
An existing EtherCAT bus is not changed here. However, in this configuration no I/O
signals can be acquired from this EtherCAT bus without further modifications.
All signals that are to be acquired via ibaBM-eCAT must be addressed directly in the
controller as output signals to the device. ibaBM-eCAT must therefore be configured as
an EtherCAT slave and integrated into the EtherCAT configuration.
This allows 512 analog and 512 digital output signals to be acquired.

9 Configuration with ibaPDA
9.1 First Steps in ibaPDA
The following instructions show you how to integrate ibaBM-eCAT into ibaPDA and to
configure the signals. You will find a detailed description of the device module "ibaBM-
eCAT" and the different modules starting with chapter 9.4.
1. Start ibaPDA on the PC and open the I/O Manager.
Find the appropriate link of the ibaFOB card to which ibaBM-eCAT is connected. Click
on the link with the right mouse button and select „Autodetect“.
If the device is correctly connected, “ibaBM-eCAT” will be shown below the link of
your ibaFOB card. The slot number corresponds to the device address, which is set
at the rotary switch.
Note
If a configuration has already been saved in the device, it
is read out with the "Autode-
tect
" function.
If there is no connection to the ibaBM
-eCAT device at the time of configuration
, it is
possible to manually add the devic
e module and the modules ("Add module") and pa-
rameterize them
.
2. If your EtherCAT master provides an export function for the EtherCAT configuration,
export it. The EtherCAT configuration file must be in XML format.
This step is necessary if the symbol browser is to be used for convenient signal se-
lection.
The export function for Beckhoff TwinCAT V2, for example, can be found at the fol-
lowing location:
Please note, that if ibaBM-eCAT is to be used as EtherCAT slave, the device must
be integrated into the EtherCAT configuration before exporting (see chapter 9.3)

ibaBM-eCAT
Manual

If no EtherCAT configuration file is available, signals can be selected for acquisition
using the EtherCAT browser (see chapter 9.4.2.3)
3. Now load the EtherCAT configuration file into ibaPDA by clicking on the link "Ether-
CAT symbol settings" in the "General" tab of the just added module "ibaBM-eCAT".
In the appearing window select the EtherCAT configuration file (either enter directly
or select via the button ).If the EtherCAT configuration file is located on a different
computer and a user ID is required, enter the UNC path, user name and password
here. Exit this window with <Load symbols>.
4. Add a module “Standard“. Click on the link “ibaBM-eCAT” with the right mouse button
and select “Add module” and the module “Standard”.
Alternatively you can click on the link “Click to add module…” and then select “Stand-
ard”.
9.2 Configuration as EtherCAT sniffer
By default, ibaBM-eCAT is preset for the sniffer functionality and the "Standard" module
for signal selection via symbol browser.
The following further steps are based on this:
1. To select the signals to be acquired with the symbol browser, click on the "Symbol
browser" link in the "General" tab of the "Standard" module.

The following window will be opened:
2. In the tree structure, select the terminals whose signals should be recorded. Open
the terminal symbol and select the signal. The signal is added to the appropriate
signal table (analog or digital) by double clicking on the desired signal or clicking on
the button <Add>.
Note
A signal must not be added twice. If a signal
is added twice to the signal table, an error
message appears when the configuration is validated by ibaPDA.
3. When all desired signals are selected close the window with a click on the button
<Close>. If required, you can add further signals later.
