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 in Consistency trigger for synchronous outputs (S.00.036),
this configured parameter is used to control the data exchange, ensuring skew does not occur; a
user program, etc, must check the configured parameter is 1 before reading the data received over
the EtherCAT network, and it should clear the parameter to 0 after all the data has been read.
The EtherCAT Module will check that the parameter is 0 before writing RxPDO destinations and will
set the parameter to 1 after the RxPDO destinations have been written.

The SI-EtherCAT module provides an input consistency feature for the synchronized cyclic data
which ensures that the data in the input mappings is only updated when the mapped parameters
are ready. This prevents data skew between parameters in the input mappings.
When the input consistency is enabled in Consistency trigger for synchronous inputs (S.00.038),
this configured parameter is used to control the data exchange, ensuring skew does not occur; a
user program, etc, must check the configured parameter is 0 before writing the data to be
transmitted over the EtherCAT network, and it should set the parameter to 1 after all the data has
been written.
The EtherCAT Module will check that the parameter is 1 before reading TxPDO sources and will set
the parameter to 0 after the TxPDO sources have been read.
