Through a browser’s File menu, the
…/ztec.pv
page can be saved as a text file to
then be modified and uploaded, or just backed up. The name of this file does not
matter in regards to uploading, but the
.pv
extension is suggested, along with a
relevant filename, in order to better track its contents.
Uploading a PV Database File
There are two methods available to update the PV Database file on the instrument. New
database configuration files can be saved to the instrument using the “Load PV
Database File” feature in the ZFind
TM
(located in the
SFP/bin
directory of a ZScopeM
®
installation) or through the command-line-based ZPVFlash utility (located within the
bin
directory of the EPICS Installation).
To upload a PV Database file using the ZTEC
®
ZFind
TM
utility,
•
Click on the desired instrument.
•
Click the EPICS icon in the toolbar (see the ZFind Users Guide for how to add an
instrument). This will bring up an interface to upload a file.
•
Browse to the new PV database file.
•
click Load File to start the upload.
The instrument will restart itself during this process, once the file has
finished uploading.
During upload, ZFind
TM
will check the PV file for errors. If an error is detected an
additional popup will appear with the option to either exit upload or continue. This is
necessary because uploading an invalid PV file will stop EPICS from booting and the
checker may not be able to compensate for drastic changes to the default PV file.
Detected errors are reported with their line number in the PV file so they may be tracked
down and corrected.
