Expansion options of the user file system
Saia PCD® systems can be expanded by at least 1 to a maximum of 4 external memory modules that contain a user system.
An external file system is ideal as a backup for the entire user application and enables users to save trend data, alarms and
event lists, as well as log files defined by the user. An external file system may contain up to 900 files or 225 directories.
The application’s system backup contains all the vital information and data
that must be available to process the application. This enables users to easily
and securely reset the controller to a saved and known state.
With the system backup function of the Saia PCD® COSinus operating sys-
tem, it is also possible to fully duplicate a system and copy it to an identical
piece of hardware with no additional adjustments required (copy/paste).
The system backup can be created in the office on a Saia PCD® memory
module using an automation device of identical construction. Any techni-
cian (without training, a manual or software tools) can then perform a sys-
tem restore or a system update direct on site should any changes be applied
– totally within the meaning of lean automation.
Creating a system backup
A system backup can also be created by the licence-freeSaia PG5® software
tool “Online Configurator”.
The system can be backed up either on the internal flash memory module
or on an optional memory module Saia PCD7.Rxxx.
Using a system backup
No dedicated software tools are required to restore a system backup. This
only requires an optional Saia PCD7.Rxxx memory module that contains a
system backup for the target controller.
Press and hold the run/stop button for 3 seconds to restore the application
contained in the backup memory module. The COSinus operating system
automatically looks for a system backup of the application in all the storage
media connected to the automation device.
If a valid system backup of the operating system is found, it is “automati-
cally” loaded into the user memory. The automation device restarts.
