Hello everyone ,

I added the Node of my process station in the Supervision Center (development station).
So I can see now the status of the process station.
Now I want to do Start Runtime Navigator on selected Node, Start Operatorplace on selected Node and Start Runtime Monitor on selected Node in the Supervision Center.

The problem is that I don't know what to enter in the Operatorplace or where the Operatorplace is when I add the Node in the Supervision Center.
The help class was not clearly enough for me to solve this problem .

I put the data structur from the process station and a screenshot of the supervision center in the attachments if this can help.

Thanks.

Best regards

Hi Maja,

The operator place is the name of an OpPlace object, Nodes-process-OpPlaces-Op, Nodes-process-OpPlaces-Maintenace or Nodes-process-OpPlaces-OpDefault. Note that you have to allow the process node to display windows on the development station.

Hello Cleas ,

Okay, so thats seems logical. So is it enough to enter "Nodes-process-OpPlaces", because in this file are all OpPlace objects?


Note that you have to allow the process node to display windows on the development station.
I only have added the name and IP-Adress of the process station and development station in the etc/hosts files in the computers (distribution etc. is working well). Is this enough for the Supervision Center or do I need to configure more things on the linux? Asking cause I am Linux beginner.

Thanks.

Hi Maja,

No, it's not enough. The rt_xtt program is running on the operator station, but it opens a display on the development station to display the window there. By default though it's closed for external access so you have to allow this. On Debian you type 'xhost +' in a termnal window, and on Ubuntu I think is some security setting.

Hi cleas,

okay, I changed the Operatorplace to "Nodes-process-OpPlaces-Op".

I will look for the external access for my Linux System (Ubuntu 16.04 Xenial Xerus)and how it works.

Thanks for your help. I will write my solutions soon as possible.


Best regards and a nice weekend!

Hello claes,

the problem is now solved and the supervision center is working perfectly!
I just needed to change three things for Ubuntu 16.04 (Xenial Xerus).

1. Open file /etc/ssh/ssh_config .
Than change # ForwardX11 no to ForwardX11 yes
and change # ForwardX11Trusted no to ForwardX11Trusted yes.

2. Ubuntu needs free ports on 6000 to 6007.
Just open a terminal and do
sudo ufw allow 6000
sudo ufw allow 6001
...
sudo ufw allow 6007

3. Open the file /etc/lightdm/lightdm.conf and add under the row [Seat:*]
this command xserver-allow-tcp=true.

4. Reboot the Proview Station or type in a terminal sudo service lightdm restart (reboot is better).

These four steps need to be done on the development station (where the supervision center is) and on the other stations (process- and operator station)for the Linux System Ubuntu 16.04 (Xenial Xerus).


Best regards and merry christmas
