Thanks for a simple implementation of the Modbus script. Such a script would be ideal for my project.
But unfortunately, I am unable to connect to the gripper when I run the script. The gripper remains in the red LED state.
I tried using it with macOS, Ubuntu 20.04, and Ubuntu 22.04, and get the same terminal output.
When I use Robotiq User Interface, I can control the gripper.
Model: Hand-E gripper
Terminal Output:
