PyTango

import PyTango

# Define the Tango device name for the Jumoquantrollc Temperature Controller
device_name = "tango://localhost:10000/sys/tg_test/1"

# Create a Tango device proxy for the Jumoquantrollc Temperature Controller
device_proxy = PyTango.DeviceProxy(device_name)

# Read the current temperature from the device
temperature = device_proxy.read_attribute("Temperature").value

# Print the temperature
print("Current temperature: {} °C".format(temperature))

In this script, we first import the PyTango module. Then, we define the Tango device name for the Jumoquantrollc Temperature Controller. This device name is in the format tango://<host>:<port>/<device>, where <host> is the hostname or IP address of the Tango server, <port> is the port number of the Tango server, and <device> is the device name.

Next, we create a Tango device proxy using the PyTango.DeviceProxy() function and pass in the device name. This proxy allows us to interact with the Jumoquantrollc Temperature Controller.

We then use the read_attribute() method of the device proxy to read the current temperature attribute of the device. The attribute name is specified as a string, in this case, “Temperature”. The read_attribute() method returns a PyTango.AttributeValue object, from which we extract the value using the value attribute.

Finally, we print the current temperature using the print() function.

Note: Make sure to replace the device_name variable with the actual Tango device name of your Jumoquantrollc Temperature Controller.
