The following script reads/writes the attributes of an ADC and a DAC. We assume that both devices are connected by a cable. Note that we set the DAC voltage limits before we change the output voltage.
#!/usr/bin/python from PyTango import * import sys import time try : dac1 = DeviceProxy( "someHost:10000/hires/exp/dac1") adc1 = DeviceProxy( "someHost:10000/hires/exp/adc1") dac1.VoltageMin = 0 dac1.VoltageMax = 10 dac1.Voltage = 3.5 print( adc1.name(), ", attr:", attr.name, "=", adc1.value) except : print( "Failed with exception !") print( sys.exc_info()[0])
