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
