Full Disk Prevention

You don't need your logger filling up your hard drive unexpectedly.

By default OPC Data Logger will stop logging when less than 100 Mb of space is free on the target disk.

You can make this value larger or smaller though we do not recommend making it smaller. 

OPC Data Logger will stop logging and notify you in the event log when it has stopped due to this condition.
