As promised, here is the pdf file of Ion Mironescu about using squeak
seaside as a SCADA (Supervisory Control And Data Acquisition ) tool
written in squeak and using seaside for the HMI.
The code is open source but not published yet.
The file is named "object oriented framework for a scada hmi" from I.
Mironescu. File is ok but pictures are not perfect, anyway it's
readable. You can download it here:
I think it deserves a sreenshot for the user section of seaside.st ;)
Thanks Ion :)
> Hi all,
> Recently, in an IFAC conf (Automatic!) in Sibiu (Romania), I was quite

> presentation of Ion MIRONESCU who I find has made an impressive job as
> part of his phd...
> He made an open-source SCADA tool (/Supervisory Control And Data
> Acquisition /http://en.wikipedia.org/wiki/SCADA) based on seaside and
> squeak. He especially uses Asteroid (for reverse AJAX, COMET), GOODS
> for the backend, and SVG to get a fancy user interface. Machine data
> are generated by a PLC proxy (written in C++) and written in GOODS.
> The web interface is updated (by comet/asteroid). The web interface
> also allows to update the database.
> I found the whole app very interesting especially for the whole
> integration aspect. As far as I know, his apps works well. He has only
> cache problem leading to some update problems ("at data production
> rate (2s-1), the browser began to miss update events or to delay
> their display"...).
> I told him ESUG and squeakers/seasiders will be grateful to see such

> month), he will polish and comment the code before publishing it. He
> will send me a paper that I'll join to another e-mail for those
