It is unnecessary for a user to set a station address manually in order to initiate EtherCAT
communications; however, this parameter can be used to configure an EtherCAT Station Alias,
which can be used to uniquely identify a particular slave. If this value is changed, it is necessary to
reset the option for the new value to take effect (e.g. by saving parameters and performing a power
cycle). If this value is left at the default value of zero, any value stored in the EtherCAT EEPROM
will be used, and if a non-zero value is stored here, it will be used in place of the EEPROM value.

The SI-EtherCAT module provides an output consistency feature for the synchronized cyclic data
which ensures that the data in the output mappings is only updated when the mapped parameters
are ready. This prevents data skew between parameters in the output mappings.
When the output consistency is enabled (S.00.036 = On), the output consistency trigger parameter
(S.00.037) is used to control the RxPDO data exchange, ensuring skew does not occur; a user
program, for example, must check the trigger parameter is 1 before reading the mapped
parameters, and it should clear the trigger parameter to 0 after all the mapped parameters have
been read. The SI-EtherCAT module will check that the trigger parameter is 0 before writing to the
RxPDO destinations and will set the trigger parameter to 1 after the RxPDO destinations have been
written.
