Because Cryocon data transfer program which sends Cryocon temperature data to EPICS in KAGRA CDS network was not working, I tried to find bug and I found that Cryocon which IP address is 172.16.34.65 did not respond to ping command from computer in CDS network. This transfer program stop if there is at least one Cryocon is not contactable. So then, I press the power button until several second to reboot this bad Cryocon. After rebooting, program worked perfectly.

 

Some infomation. Data transfer program is written in K1CRY_CRYOCON_DAQ.py, and running every minutes using crontab. All channels we want to transfer from Cryocon to EPICS in CDS network are listed up in K1CRY_CH_LIST.txt. 
Because this data transfer script only send data from Cryocon to EPICS, we need .db file to regist database in EPICS IOC and also need .ini file to recorde EPICS data in framefile in KAGRA.

 

These files are locate such as
