I switched the script to generate the segment files (running at k1det1) to the prepared new one (see klog). From 5/30 0:00 UTC, the DAC overflow of ETMX with LPCD is checked for the automatic segment production. I confirmed the replaced script is running well every 15 minutes. This update was also applied to the Kashiwa cluster.
Thanks to this work, we don't need to modify the script to fit the commissioning of switching the coil driver.
