Connect to the Agilis in Python

PROTOCOLS > SCPI

To connect to an Agilis Positional Controller using Instrumentkit, you can use the following code:

from instrumentkit import serial
from instrumentkit import newport


# Connect to the controller
port = serial.SerialPort("COM5", baudrate=921600)
controller = newport.AGUC2(port)


# Reset the controller
controller.reset_controller()


# Print the firmware version
print(controller.firmware_version)


# Move the X axis relative by 1000 steps
controller.axis["X"].move_relative(1000)


# Activate jogging in mode 3 for the X axis
controller.axis["X"].jog = 3


# Stop the X axis
controller.axis["X"].stop()


# Query the step amplitude for the X axis
step_amplitude = controller.axis["X"].step_amplitude
print(step_amplitude)


# Set the positive step amplitude to +10 and the negative step amplitude to -20 for the X axis
controller.axis["X"].step_amplitude = (10, -20)


# Close the connection
controller.close()

This code connects to the Agilis Positional Controller on COM5 with a baud rate of 921600. It then performs various operations such as resetting the controller, printing the firmware version, moving the X axis relative by 1000 steps, activating jogging in mode 3 for the X axis, stopping the X axis, querying and setting the step amplitude for the X axis. Finally, it closes the connection to the controller.
