Identification
This activates the function and releases the necessary parameters.
Identification
Mode
Assign identification ID to slave so that the EtherCAT master knows the
order of the added devices (will not be written on slave).
The following options are available for selection:
● Configured Station Alias: To identify the device the configured Sta-
tions ID is used.
● Requesting ID mechanism: Identification ID is configured at the de-
vice (e.g. via DIP switch).The address offset 134 is used here.
● User-defined Address Offset: Any address offset can be indicated
here. Which setting needs to be carried out here, can be found in
the documentation of the EtherCAT slave device.
Address Offset
Is only configurable if the identification mode "User-defined Address Off-
set" is used.
Station ID
Station Alias of the EtherCAT slave device for unique localization of the
device on the EtherCAT bus (0: Position of the device on the bus will not
be checked).
For certain use cases it is necessary to assign an additional address - the
"Device identification value" - to an EtherCAT slave device. This address can
either be configured at the device via DIP switch or it can be written as "Sta-
tion Alias" to the EEPROM of the device. This is to localize the devices on
the bus. The assigning of this address is necessary for the following use
cases:
● Use of several similar EtherCAT slave devices on the bus whereat the
order of this devices is important for the function of the system. During
the bus scan it can be recognized if devices are interchanged.
Use of several similar EtherCAT slave devices on the bus whereat at
least one of the devices is optional. During bus scan it is recognized on
which position which optional device is connected or not connected. So
the correct order of the devices is maintained.
The Station Alias for an EtherCAT slave device can be configured via u-cre-
ate studio.
