Hi all,
I would like to use Eclipse neoSCADA in few big projects, but I still have some terrible doubts. Could you please give me answers on the most important questions?
1. What is the maximum number of TCP connected clients may support server?
2. Is it possible to transfer files through Eclipse neoSCADA from user client (or user web interface) to remote embedded device?
3. Is it possible to setup web ui for the user with the authorization feature?
4. How can we to differentiate the rights of users?
5. How the user client application gets its interface?
6. Is there a working demo Eclipse neoSCADA servers on the internet that can be connected via demo client application running on my PC (I can't connect to the demo NeoSCADA servers from this topic: https://wiki.eclipse.org/EclipseSCADA/GettingStarted/DemoSystem)?


Thanks in advance for answers!

I received email with answers from scada-dev-request@eclipse.org:
Maybe it will be useful for someone.

1.) This depends on your setup. If you put everything on one node, then
it is the maximum number of TCP clients your resources can handle. I am
not aware of any limit at the moment. If you start to split up processes
to different nodes, then you can handle even more of course. If course
this also depends on which protocols you want to use, which types of
connections, etc..

2.) No. It is not a file transfer application.

3.) Currently there is no Web UI only a rich client

4.) Using a rule based system which can be configured during runtime and
make decisions based on JavaScript logic and XMLSIG validation

5.) By creating "VI" models, which are a mixture of XML files and
JavaScript update logic. There is a structural editor for those XML
files and a preview. In addition there are form based dialogs which can
also be created by using a set of pre-defined form elements using XML files.

6.) Not right now, as it seems. I just did check the "scada.eclipse.org"
instance. But it is down. I don't know why, but I will dig into this.
The "openscada" server is decommissioned and I did remove the link from
the wiki.
