Subject: About SCADA
Date: Thu, 02 Nov 2006 21:29:38 +0100
Hello,
I'm a Spanish developer who is working in a SCADA environment for an=20
Spanish chemical company and I'm developing it with QT4 under Linux.
Surfing in the web I found your project which it's very similar to mine=20
;) ... as soon as I finish with this I'll try to help you in some areas=20
of your project if it doesn't takes a lot of time (because I'm very=20
busy now) - If you need help in some area write me and I'll try to help=20
you ;)
Also, I want to make a little question about my project ... It's the=20
first time I work with PLCs so I'm a "Rockie" in this area :D ... My=20
main questions are:
1.- Is there any OMROM or SIEMENS emulator to test the SCADA=20
communications with it?
2.- Is there any library to communicate with OMROM (hostlink) and=20
SIEMENS (profibus?) in Linux? (no problem if it a commercial solution)
3.- Is there any good OPC for Linux? I saw a lot of it for Windows, but=20
I don't want to use it in a production enviroment and I prefer to use=20
the XML-DA protocol versus COM/DCOM ;)
My main idea of the project is a dedicated machine with Linux getting=20
information from all the plant PLCs and store all the sensors values in=20
a database (postgresql or MySQL), then the SCADA GUI will communicate=20
with the DB and show the information to the user.
My problems now are in getting information from the SCADA because I am=20
very far from the company so I need an emulator or something similar or=20
buy a developed environment.
Thanks,
Fernando.
