Subject: Archiver Appliance scripted alias record

Hello,

 

Is it possible to add a fake, aliased PV to the Archiver Appliance and then populate its history from another PV being stored. I have a waveform record that I have been recording but I need individual PVs for each index. I could store the waveform and then the (200 odd) individual PVs. However, this looks like a nice job for a script:

 

So, I have my 200 array waveform being archived:

EBT-SOMESTUFF:BAR

 

Then a script running on the archiver looks for a request like so and returns the first index of the waveform BAR:

EBT-SOMESTUFF:BAR:M1

 

EBT-SOMESTUFF:BAR:M2  gives the second index of :BAR etc…

 

If it is possible, could you point me in the direction of some scripting examples for the archiver. If it would not be possible or too complex, I can do this in code at the client end.

 

Regards,

 

Rory
