How to enable external communication with KUKA Sim?

Hello,

I’m currently working on a project where I need to establish communication between KUKA Sim and an external system. Previously, I successfully communicated between RoboDK and a real KUKA robot. In that setup, I used the RoboDK driver and set up a proxy server, specifically C3 Bridge, on the KUKA robot controller to facilitate communication.

Here’s a brief overview of the data flow in my previous setup:

1. Movement commands were generated in RoboDK.
2. These commands were sent to the KUKA robot controller via the RoboDK driver.
3. The C3 Bridge on the KUKA controller interpreted these commands, modified the variables in the $config file.
4. The KUKA controller then executed the corresponding KRL commands based on the changes in the $config file, resulting in the robot’s movement.

Now, I’m in an environment where I cannot use a physical KUKA robot. Instead, I want to use KUKA Sim to communicate with RoboDK in a similar manner. My main questions are:

1. Is it possible for KUKA Sim to communicate with external systems (like RoboDK) and allow modification of variables in the $config file?
2. Can C3 Bridge be used with KUKA Sim to enable this communication?
3. How can I establish real-time communication between KUKA Sim and an external system to modify $config variables dynamically?

Any guidance or suggestions on how to achieve this would be greatly appreciated.

Thank you!

Additionally, in the attached file, the sections highlighted in red are the $config and the variables I mentioned.

Quote from panic mode

KRC simulator is called OfficeLite.

that is what previous versions of KukaSim used. and OfficeLite behaves like real KRC so integration of C3B or KVP is the same as on real KRC.

Newer versions of KukaSim includes OL functionality. Not sure how you would use C3B or KVP there

Thank you for your response!
From what I understand, since KUKA Sim and the actual KRC serve the same functions, C3B should also operate in the same way.
However, in my case, it didn’t work as expected. Let me explain how I used C3B:

1. I ran C3B on a computer, let’s call it PC1, with a network IP, for example, 192.168.1.123.
2. Then, I launched RoboDK on PC1 and ran the driver, establishing a connection (with the network IP of PC1 set to 192.168.1.123 and the port to 7000).
3. I confirmed the connection between RoboDK and C3B.
4. I ran KUKA Sim on the same computer, PC1, and on the same network.
5. I executed a prepared KRL program in KUKA Sim.
6. When I sent a system variable request and executed the 'Get position' command from RoboDK, there was no response.

In this setup, the connection between RoboDK and C3B worked fine, but it seems that the connection between C3B and KUKA Sim did not.
Therefore, I would like to understand how C3B connects to KRC’s KSS.
In the case of an actual robot, it seems that when C3B is installed and running within the KRC, it automatically connects internally with KSS.
However, this doesn’t seem to be the case with KUKA Sim.
