4. Configuration
145
Check VendorID and ProductID: By default, at startup of the system the Vendor ID and/or the
Product ID will be checked against the current configured settings. If a mismatch is detected, the bus
will be stopped and no further actions will be executed. This serves to avoid the download of an
erroneous configuration. This option is intended to switch off the check, if necessary.
SDO Access: By default there’s no timeout set for the SDO list submit action at system startup.
However, if it’s necessary to check if this action exceeds a certain time, it must be defined (in
microseconds) in this field.
I->P: By default there’s no timeout set for the state transition between Init to Pre-Operational.
However, if it’s necessary to check if this action exceeds a certain time, it must be defined (in
microseconds) in this field.
P -> S / S-> O: By default there’s no timeout set for the state transition between Pre-Operational to
Safe-Operational and between Safe-Operational to Operational. However, if it’s necessary to check
if this action exceeds a certain time, it must be defined (in microseconds) in this field.
DC cycle unit control: Choose the desired option(s) concerning the Distributed Clock functions in
order to define, which should be assigned to the local microprocessor. The control is done in register
0x980 in the EtherCAT slave: The possible settings: Cyclic Unit, Latch Unit 0, Latch Unit 1.
Station Alias: These settings are only visible if the option Optional is activated or if the slave device
supports alias addresses (defined in the Device Description File).
Enable: If the setting Optional is not activated, this setting can be activated if explicitly supported by
the device description of the slave. It allows direct assignment of an alias address in order to get the
slaves address independent of its position within the bus. If the option Optional is activated, this
checkbox is disabled.
Write to EEPROM: This command is only visible in online mode. It allows to write the defined
address to the EEPROM of the slave. If not supported by the slave this command will have no effect
and the device will not work as Optional Slave.
Actual Address: This field, only visible in online mode, displays the actual address of the slave. It
can be used to check the success of the Write to EEPROM command.
FMMU/Sync
This dialog will only be provided on a tab of an EtherCAT Slave configuration editor if the
Autoconfig Mode in the Master is disabled. It shows the FMMUs and Sync Managers of the slave as
defined by the device description file. These settings may be reworked, for example for configuring a
slave-to-slave communication.
ATTENTION:
These are Expert Settings, which usually are not necessary for standard applications.
