Standard PCD-Web-Server CGI interface
The COSinus integrated HTTP web server has a standardised Common Gateway Interface (CGI). The CGI interface supports
the direct access (reading and writing) to all PCD media (register, flags, DB/texts, I/Os, etc.) and the file system (up/download,
delete, etc.)
A client (browser, Java or MS.Net application) can then access the data on a PCD controller by entering the URL
and corresponding CGI command directly (without using specific drivers).
The Saia PCD® Web-Server
processes requests/orders via the
CGI interface and sends the client
the requested information.
Microsoft.Net or Java already
have the categories “WebRequest”
and “WebResponse” available for
requests made to a web server.

The Saia PCD® Web-Server provides an open CGI interface in addition to the HTTP server.
SBC.Net Suite
The SBC.Net Suite includes components and class libraries for communicating via S-Bus (master and slave)
or the CGI interface. It allows the basic integration of Saia PCD® data in a Windows application without
having to worry about communication drivers (middleware) or CGI syntax. Further information can be
found in Chapter B1 Software.
Accessing the Saia PCD®Web-Server with MS Office applications
Microsoft Office products support the integration of external web sources.
This makes it very easy to visualise the data of a Saia PCD® controller in an
MS Office application. The MS Office products can also access via the CGI
interface of a Saia PCD® Web-Server to read or write data using the VBA
programming language.
X
Saia PCD® data can be linked to a cell using
Microsoft Excel. The data in the linked Saia PCD®
will be permanently updated for as long
as the Excel application is running. All this occurs
without any of the specific driver software/
middleware required by other systems.
