Installing a VcExecutor (Virtual Counter)

This is the general procedure to prepare a virtual counter, explained by an example returning the time (Jan Kotanski):

• create a VC script, e.g. using python `time.time()` or `datatime.datatime` and save it in to some directory e.g. /usr/local/experiment/Tango/VcCode/ (you can check `VcCode` properties of your other VcExecutors)

• run jive: Edit -> Create Server -> ...

  for example:

    
     Server:
         VcExecutor/SystemTime
     Class:
         VcExecutor
     Device:
         p23/vcexecutor/systemtime
  

• set its VcCode Property in jive to /usr/local/experiment/Tango/VcCode/<my_script.py> where <my_script.py> is the name of a script you have created

• start new server VcExecutor/SystemTime in astor

• add the VcExecutor to online.xml

    
  <device>
   <name>systemtime</name>
   <type>counter</type>
   <module>counter_tango</module>
   <device>p23/vcexecutor/systemtime</device>
   <control>tango</control>
   <hostname>hasep23eh:10000</hostname>
  </device>
  

• run SardanaAIO.py -x
