The following script shows how an input register senses the state of an output register.
#!/usr/bin/python from PyTango import * import sys import time try : ireg1 = DeviceProxy( "hires/exp/ireg1") oreg1 = DeviceProxy( "hires/exp/oreg1") attr=ireg1.read_attribute( "Value") print "ireg1, value ", attr.value attr.value = 1 oreg1.write_attribute( attr) attr=ireg1.read_attribute( "Value") print "ireg1, value ", attr.value attr.value = 0 oreg1.write_attribute( attr) except : print "Failed with exception !" print sys.exc_info()[0]
