Issue Details

I am using a National Instruments E Series DAQ device to handle sensitive data. Will this data be cleared when the device loses power?

Solution


Here is a list of the current information on some of our E Series boards. The list below contains the types of memory in each device, the amount, and whether or not the information stored in that memory is retained. Volatile memory loses its contents when the device is powered off while nonvolatile memory retains its contents when the device is powered off. 


The following table applies to these devices:
  • PCI-MIO-16E-4/PCI-6040E/PXI-6040E
  • PCI-MIO-16XE-10/PCI-6030E/PCI-6031E/PCI-6032E/PCI-6033E
  • PXI-6030E/PXI-6031E
  • PXI/PCI-6052E
  • PXI/PCI-6070E 
  • PXI/PCI-6071E
 Storage TypeSizeVolatilityAccess Restrictions

Calibration EEPROM4k

NonvolatileNot write protected. This EEPROM contains calibration information that is stored when the device is calibrated. There are also 5 characters (10 bytes) that can be written by the user through the DAQmx API. See linked KB below for information on clearing this section of the EEPROM.
MITE EEPROM8k x 8NonvolatileA hardware change is required to write to this EEPROM. No user data is stored.
During normal course of operation, no user data is stored in the device after power is removed.


The following table applies to the AT-AO-10:

During normal course of operation, no user data is stored in the device after power is removed.
