Issue Details

I'm logging data using cDAQ-9136 with Windows Embedded Standard OS(WES7). When I unplug power cable while code is running, file remains but the contents are deleted. 


Unlike our real-time operating systems, Windows is more susceptible to disk corruption when power is lost during operation. To prevent data loss from unexpected power off, adding proper power redundancy might be an option. 

With the majority of CompactDAQ and CompactRIO controllers, you can use a dual-input power connector plug with a V1 for a primary power input and a V2 for a secondary power input. Check the product's user manual to see if the controller in question includes the dual-input power connector plug. This gives you the option of adding a second power source to your system, so it can still operate without disruption if your main power supply is no longer providing sufficient voltage, potentially due to a blackout or brownout situation.
