Fig. 67: Detected Ethernet devices
After confirmation with “OK” a device scan is suggested for all selected devices, see Fig. 5.
Note
Selecting the Ethernet port
Ethernet ports can only be selected for EtherCAT devices for which the TwinCAT real-time
driver is installed. This has to be done separately for each port. Please refer to the respec-
tive

Detecting/Scanning the EtherCAT devices
Note
Online scan functionality
During a scan the master queries the identity information of the EtherCAT slaves from the
slave EEPROM. The name and revision are used for determining the type. The respective
devices are located in the stored ESI data and integrated in the configuration tree in the de-
fault state defined there.

Attention
Slave scanning in practice in series machine production
The scanning function should be used with care. It is a practical and fast tool for creating an
initial configuration as a basis for commissioning. In series machine production or reproduc-
tion of the plant, however, the function should no longer be used for the creation of the con-
figuration, but if necessary for
comparison [

with the defined initial configura-
tion.Background: since Beckhoff occasionally increases the revision version of the deliv-
ered products for product maintenance reasons, a configuration can be created by such a
scan which (with an identical machine construction) is identical according to the device list;
however, the respective device revision may differ from the initial configuration.
Example:
Company A builds the prototype of a machine B, which is to be produced in series later on. To do this the
prototype is built, a scan of the IO devices is performed in TwinCAT and the initial configuration ‘B.tsm’ is
created. The EL2521-0025 EtherCAT terminal with the revision 1018 is located somewhere. It is thus built
into the TwinCAT configuration in this way:
