hi, xiaoqiang:

Thanks a lot for your letter. In fact, pcaspy is very convinent and helpful for me, thanks for your work.

I have another question, can scan field be set to a arbitrary value such as 0.001? If it can work, corresponding, the server.process(0.01) will be set instead of server.process(0.1)?

Hi,

 

According to

http://www.aps.anl.gov/epics/base/R3-14/12-docs/CAref.html#Configurin2,

you can set EPICS_CAS_SERVER_PORT

 

# on the server side

$ export EPICS_CAS_SERVER_PORT=5078

$ python dummy.py

 

# on the client side

$ export EPICS_CA_SERVER_PORT=5078

$ caget MTEST:RAND

MTEST:RAND 0.000 (SEVR:INVALID STAT:UDF)

 

But if the same driver is instantiated for many devices, you can create

the database with different prefixes.

 

if __name__ == '__main__':

     ...

     prefix = sys.argv[1]

     server.createPV(prefix, pvdb)

     ...

 

Then to run the server for each device

$ python dummy MTEST1:

$ python dummy MTEST2:

 

Best

Xiaoqiang
