version 5.8.1 not working on ubuntu 20.04

[JW]

after installation, error message on login page “Server is unavailable”.

no log file generated in /opt/scada/ScadaServer
the log in /opt/scada/ScadaWeb/log is attached below

I change back to 5.8.0, then everything works fine.

You probably did something wrong, I have 5.8.1 running and running on Raspberry Pi 3

[manjey73]

sudo service scadaserver status
sudo service scadacomm status

???

[Mikhail]

The issue is not related to the version.
You should check the log of the Server service to find the cause.

Are ScadaData.Svc.dll in ScadaServer and ScadaComm folder needed for version 5.8.1?

I copied those 2 files from 5.8.0 to 5.8.1. It seems working now.

[manjey73]

Have you completely copied all the files, including the daemon files ? Do you remember to distribute the rights to the corresponding files and folders as during installation ? I just copied only the required files, but I didn’t even touch the demons, and my system started up. In your case, you either do not have the services themselves (it may be related to rights), or some files are unavailable when you start the services.

[manjey73]

No, I don’t have it in my folder ScadaData.Svc.dll

Hi manjey73, thanks for your help.

it turns out it wasn’t the ScadaData.Svc.dll make it work. it was the daemons of 5.8.0 make it work.

I tried the following tests:
1. fresh install of 5.8.1, does not work;
2. fresh install of 5.8.0, work;
3. update /opt/scada to5.8.1 + keep daemons from 5.8.0, work.

the file size and edit time are slightly different between 2 set of daemon files, but i can’t find the difference between the content.
5.8.0———-

[JW]

here maybe the root cause.

the line different from 2 version in daemon files scada
5.8.1
EXE_DIR=/etc/scada/ScadaServer/
5.8.0
EXE_DIR=/opt/scada/ScadaServer/

[manjey73]

Yes, I did not transfer daemons, because I have Scada installed in the user’s home directory and I fixed the paths to exe files in them, as well as added a string of rights changes to some files after restarting the server.

[Mikhail]

There was an error in scadacomm and scadaserver scripts. Now it is fixed. Thanks.

Hi,

I’m a newbie in RS and ubuntu. and I have installed RS on ubuntu 16.4.

That I want to ask, how to use scada administrator as in the video tutorial in windows OS ?

I tried to use software “Wine” to open Scada Administrator, but when creating a project, I was stuck when adding a device with the words “Error getting device interface type from the library KpSimulator.dll: Absolute path information is required.
Parameter name: assemblyFile ”
(Google Translate)

Thanks a lot,
Regards,

Isnan
