The SI-EtherCAT module provides an input consistency feature for the non-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 (S.00.042 = On), the input consistency trigger parameter
(S.00.043) is used to control the TxPDO data exchange, ensuring skew does not occur; a user
program, for example, must check the trigger parameter is 0 before writing to the mapped
parameters, and it should set the parameter to 1 after all the data has been written. The SI-
EtherCAT module will check that the trigger parameter is 1 before reading the TxPDO sources and
will set the trigger parameter to 0 after the TxPDO sources have been read.
