Using the Internal Real-Time Clock on cRIO-901x Controllers Hardware: CompactRIO>>Controllers>>cRIO-9012, CompactRIO>>Controllers>>cRIO-9014
Problem: In the manual for the cRIO-901x Controllers it states the following: "The system clock of the cRIO-9012/9014 is synchronized with the internal high-precision real-time clock at startup. This synchronization provides timestamp data to the controller. You can also use the internal real-time clock to correct drift of the system clock." How can I use the internal real-time clock to correct drift of the system clock? Solution: To use the internal real-time clock to correct drift of the system clock add the following lines to the ni-rt.ini file for the controller. You will need to FTP this file onto a Windows machine, make the changes, and FTP the modified file back to the controller. After updating the ni-rt.ini file, the cRIO-901x controller will automatically implement the GPS drift-correct based on the input Pulse-Per second input. [Time Sync] Related Links:
