Exception: A connection with systemId {...} has already been added

RobotStudio

Hi,

I know, this point is already in this forum, but in my case it is not a Developer Tool issue. (ABB Robotics Community - Maintenance)

I have the error: A connection with systemId {…} has already been added.
I use now RobotStudio 2012.2. What I did:

  • connected to a real robot on the service port: 192.168.125.1, that works
  • connected to the same real robot via pc-interface and a fix IP-address: 194.147.106.95, does not connect and I get the error: A connection with systemId {…} has already been added.
    I just see the connected robot in the controller window on the left, but there is nothing below, like RAPID.

With previous versions of RobotStudio I did this quite often, and that worked.
For remote access we need that pc-interface connection.

What can I change?

As workaround, can I edit this systemid list and delete the old connection on the service port?

Best regards
Marcel

Hi

The reason for this problems could be that my company has changed something in the network-settings of my company laptop. So the priority for the network connections is different now. As I cut all the other (Wifi) connections, the laptop could now connect to the pc-interface with the fix IP-address: 194.147.106.95. A detail: onto the service-port I go via Wifi to an access-point.
With other RobotStudio versions: 2021.1.2 and 2020.4 I have got the same effects as described in the beginning.

Best regards
Marcel
