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?

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.

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.
