Lexium Cobot Integration with SCHUNK Gripper: Questions and Insights

Hello everyone, I’m currently working on integrating a SCHUNK EGP 40-N-N-IOL Gripper with the Lexium Cobot. My setup involves using a Balluff IO-Link Master as an intermediary device to enable communication between the gripper and the cobot. Here’s what I’ve done so far:

  • The SCHUNK gripper is connected to the IO-Link Master via an M12 IO-Link port.
  • The Balluff IO-Link Master is connected to the Lexium Cobot Compact Controller via Ethernet/IP.
  • The goal is to control the gripper (e.g., open, close, adjust force) directly from the Lexium Cobot controller or any other program on my PC.

I have a few questions and would appreciate any guidance:

  1. Is using the Balluff IO-Link Master the correct approach for enabling communication between the cobot and the gripper? Are there better alternatives, or does the proposed setup look fine?
  2. How can I configure Ethernet/IP communication between the Lexium Cobot and the IO-Link Master? Any specific settings or considerations I should be aware of?
  3. What is the best way to send gripper commands (open/close) through the cobot controller? Would scripting with the Lexium Cobot Programming Script be required?

Additionally, I have the following resources available:

  • GSDML file for the IO-Link Master
  • IODD file with device description for the SCHUNK gripper EGP IOL

I would greatly appreciate any insights, resources, or recommendations to help establish communication and control between the Lexium Cobot and the SCHUNK gripper. If anyone has experience with similar setups or can suggest alternative approaches, please share your thoughts!

Thank you in advance for your help!
