Counter and Timer

The following script shows how a counter and a timer are operated together:

• SampleTime is set to 1s.
• The counter es resetted (cleared).
• The timer is started.
• The script waits until the timer expires.
• The counter contents is displayed.

#!/usr/bin/env python
from PyTango import *
import time

try :
    counter = DeviceProxy( "someHost:10000/p15/counter/exp.01")
    timer = DeviceProxy( "someHost:10000/p15/timer/exp.01")
except :
    print( "Failed with exception !")
    print( sys.exc_info()[0])
    exit

timer.SampleTime = 1.0
counter.Reset()

timer.Start()

while timer.state() == DevState.MOVING:
    time.sleep(0.1)
    print( "remaining %g" % timer.RemainingTime)

print( " counts %d " % counter.Counts)
