The Saia PCD® contains the master control and management functions for many
distributed systems or large integrated buildings.
Client & server in one device: The Saia PCD7.D4xxxT5F
micro-browser panels are simultaneously server and client.
The demanding control function can be realised using the
Saia PG5® software tool.

Dimensioning the data storage for S-Web applications
The dimensioning of the data storage must take into consideration the size of the web project and the historical data (trend data)
which needs to be stored. The following reference values can be used as guideline to provide a rough estimate.
Memory requirement for S-Web pages:
The calculation of the memory requirements for web pages is based on the number of web pages, number of GIF graphics used
and the IMaster Java applets. The following reference values can be used as guideline to provide a rough estimate.
S-Web page
approx.10 kByte/page
GIF graphics
1…10 kByte
Java applet
approx.350 kByte
A project with 30 HMI pages will therefore need approx. the following memory requirement:
(30 × 10 kByte) + (100 × 5 KByte GIF graphics) + 350 kByte
= memory requirement for web project approx. 1150 kByte
