The Di driver (NI DIDS cRIO9066, 9411, 9751)was working correctly, but after replacing the PC I had a problem. The power supply could not be turned on/off by software(SCM2015) with DI driver (cRIO9066, 9411, 9751×2) .The cause is the communication failure with the TDK lambda HV unit according to the log. Therefore, the following was implemented, but it has not solved. The driver update .exe I got from HPL before can't be used in the target license error log. (It was used before.)Also, I tried Restor using .zip file.The cRIO status is that the USER1 LED blinks three times and the TDK Fault log is in the same state.
