Karabo

Installation

Installation instruction can be found at https://rtd.xfel.eu/docs/karabo/en/latest/installation/index.html

SSH tunnel

To start the karabo-gui from outside the control network, you need to first create a ssh tunnel:

ssh desyusername@exflgateway -L 44444:scs-rr-sys-con-gui1:44444

where desyusername is your desy login. The target host must be scs-rr-* for the SCS topic or sa3-br-* for the SA3 topic. In addition you can chose either *-gui1 or *-gui2.

Starting the GUI

Once the tunnel is in place, open a new terminal, or if you are already in the control network, simply type in:

source ~/karabo/activate
karabo-gui &
../_images/karabo-gui-connect-to-server.png

Karabo connect to server.

Click on the ‘connect to server’ icon, as shown in karabo-connect-to-server and either connect to 127.0.0.1 with 44444 port if you are outside the control network and use the ssh tunnel you created or connect to scs-rr-* or sa3-br-* if you are in the control network. Always connect as admin.

Karabo and Beckhoff

Most beckhoff devices (motors, encoders, gauges, valves, …) are not instantiated from within a project. Such devices can be instantiated using the Beckhoff assistant:
