Hi Florian,

I'm currently working together with the company iseg Spezialelektronik GmbH
to develop EPICS device support for their high voltage power supplies.

Two questions came up so far:
1) It is possible that some Control values change their values.
     Can the device support in such a case change the value of a bo record?
     Will the record be processed when changing its value from device
support?

Yes. See
   http://www.aps.anl.gov/epics/tech-talk/2014/msg01947.php
and the other mails of that thread for more details.

2)  Is it possible to give this timestamp through the device support to
the record?
     From the record reference manual I guess not...

This is supported via setting the TSE field to "-2". Documented at:
   https://wiki-ext.aps.anl.gov/epics/index.php/RRM_3-14_dbCommon

Hope this helps,
~Ralph
