The NI-9145 has an EtherCAT safe state that the device passes through when moving from LabVIEW Active Mode to LabVIEW Configuration Mode. The NI-9145 passes through the EtherCAT safe state during normal operation or in case of a serious error.

In the EtherCAT safe state, output modules are set to pre-defined safe values. By default, zero is the safe value in the output module channel configuration. You can change the safe values by writing to the appropriate object dictionary entries for your output module.
