PROTOCOLS > SCPI

📄 IDN

Query a device's identity through the universal *IDN? SCPI command.

📄 MEASURE VOLTAGE

Query an instrument's measured output voltage, such as a DMM or power supply.

📄 SCPI WRITE

Write a SCPI command to a connected bench-top instrument and return the result.

InstrumentKit

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.
