Enable TELNET on your robot

Telnet KCL allows you to send commands to a Fanuc robot, such as resetting alarms, writing variables, setting an IO, and more. This feature is natively available on all Fanuc robots without requiring any additional options.

To enable a TELNET connection on your real or simulated ROBOGUIDE robot, please follow the instructions below. On a real robot, the connection is established via TCP on port 23. In ROBOGUIDE, while this port is open, it only allows read-only access. Therefore, to enable full bidirectional communication via Telnet, you must follow the provided instructions to set up a dedicated alternative port.

This library allows you to send KCL (Karel Command Language) commands over the TELNET connection.

1. Set a TELNET password

Adding a password is mandatory to enable telnet control of the robot.

• Press MENU on the robot's teach pendant.

• Select SETUP / -- NEXT -- / Host Comm

• Select TELNET and press DETAIL

• Add a password to the KCL feature

• Press ENTER and PREV on the robot's teach pendant to validate this password.

• Cold start your robot

2. If you have option J541 (Password Protection)

<PASSWORD>
  <PWD level="0" const="1" access="1"/>
