System Clock Update Time in Real-Time Hardware

Issue Details

Solution

• The system clock is updated from the BIOS at boot. System time can be corrected by booting into the BIOS.

• There are different ways system clocks operate on cRIO and myRIO controllers. In general, the system clock of both are synchronized with the internal high-precision clock at startup (when power is supplied to the chassis). This synchronization provides a timestamp to the controller. Note that not all cRIOs and the myRIOs do not have a battery backup, so a loss in power will reset the clock. Please check the relevant user manual to see if your cRIO chassis has a battery backup.

• The controller's system clock can be set by specifying a Time Server in the Network Settings Tab of your [c]FieldPoint 20xx.  The time server updates the system time of the FieldPoint controller at boot. 
• If no Time Server is specified, the date and time can be set programmatically using the RT Set Date and Time.vi.
