Hi Mark

 

No they are something else, specifically they are Libera devices from I-Tech. For example on the Libera electron I managed to get the NTP working by setting the hardware clock using “hwclock”, writing “/etc/ntp.conf” pointing to our NTP server then running the NTP daemon but the Libera BLM for example can’t set the hardware clock because it can’t find “/dev/rtc”.

 

We are in talks with I-Tech to solve the issue but I want to know if such configuration can be done on the archiver side. For example, “camonitor –t c” gives you the correct timestamp (local one), so I imagine EPICS somehow can be configured in such manner.

 

Thanks!

Abdalla.

 

 

Are these hard-IOCs vxWorks, RTEMS, or something else?  On vxWorks you should be able to make NTP work.

Hi

 

We have an issue when we want to archive PVs from a hard-IOC based device. The issue is that these devices don’t have the time set correctly and most likely somehow NTP won’t work. This causes an issue archiving these PVs because, if I understand correctly, the archiver takes the timestamp from the channel access not the local one. Is there a way to configure the archiver appliance to take the local timestamp instead of the CA one?

 

Best Regards,

Abdalla.
