Dear Xiaoquiang,

Thanks for the information.

What is important to me is also to have a proper timestamp for the PVs

and I an not very confident on the windows machine.

If I install a portable channel access server, the timestamps of the PVs

I serve there will be taken from the windows machine; am I right? If I

have the server in other computer the timestamp of the uploaded PV will

be given by that other server, not the "caput" operation I run in the

windows; isn't it?

Best regards,

Zunbeltz

Hi,

There is a 3rd choice: create the PV in portable channel access server.

If your calculation code can be invoked with Python, be it a C extension or separate program (using subprocess module).
This can be easy to write using PCASpy[1] extension.

Dear all,

We need to pass some values, calculated from photographs, to the EPICS network from a windows machine.
Is it easy to install an IOC server in a windows machine?
If not, our idea is to create the PVs in an already running IOC server (on linux), and use caput tool (from the EPICS Extensions http://aps.anl.gov/epics/distributions/win32/index.php) to update the values.
Is it possible to create an  PV that is not associated with any hardware in a IOC server? Is it enough to add a record in the ioc.db file?

Thanks in advance for your help.
