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

hi,

   I would like to ask if  SimpleServer's port can be changed to others
in code, such as 5066/5068? For example, I have a device driver written
by pcaspy, I want to implement the same driver for many same type
devices on one machine, then I need to set them different server ports.
   thanks a lot for your help.


Best wishes
