Saia PCD® Opcode
Saia PG5® generates a platform-independent opcode that is in-
terpreted by the Saia PCD®. As a result, the same program runs on
different platforms. This also enables the user program to be updated
with a flash card as the operating system of the Saia PCD® performs
the necessary actions to copy and execute the program from the flash
card to the memory.
Code that is generated (= compiled) and optimised for the specific
platform will of course run faster. This compiler is not integrated into
the PC tool (Saia PG5®). Saia PCD® COSinus knows how this code
should be implemented into the relevant hardware most effectively.
The program is compiled when it is loaded into the Saia PCD®.
Automation server
The Automation Server is part of the COSinus operating system.
It includes widespread web/IT technologies and ensures data
exchange between users and automation solutions with no pro-
prietary hardware or software required.
Specifically adjusted automation functions and objects form the
relevant counterpart in the controller application. The web/IT
functions can therefore be optimally and seamlessly integrated
into the automation device and used efficiently.

Execution
Web server:
The system and process are visualised in the form
of web pages and can be requested from the
web server via browsers such as Internet Explorer,
Firefox, etc.
File system:
Process data, records, etc. are stored in easy-to-
access files. Standard formats make it easy
to process them further, e.g. with Microsoft Excel
FTP server
Load files into the automation device over the
network using FTP, or export files from it.
Email:
Critical system statuses, alarms and log data can
be sent by email.
SNMP:
Messages and alarms are transmitted in accordance
with IT standards. Access to automation data using
the IT management system.
Automation Server components
