Clause / Requirement

14.5The storage of programs and data (see also Annex C)

14.5.1All executable code and data necessary to comply with this European Standard shall be held in memory that is capable of continuous, unmaintained, reliable operation for a period of at least 10 years.

14.5.2For the program, the following requirements shall

apply:

athe program shall be held in non-volatile memory, which can only be written to at access level 4, and

bit shall be possible to identify the version reference or references of the program at access level 3. The version reference or references shall be in accordance with the documentation of 14.2.1.

14.5.3For site-specific data, including emergency message(s), the following requirements shall apply:

athe alteration of site specific data shall only be possible at access level 3 or 4;

bthe alteration of site specific data shall not affect the structure of the program;

cif stored in read-write memory, there shall be a mechanism which prevents the memory being written to during normal operation at access level 1 or 2, such that its contents are protected during a failure in program execution;

dIt shall be possible to either read or interrogate the site specific data at access level 2 or 3, or the site specific data shall be given a version reference that shall be updated when each set of alterations is carried out.

eIf the site specific data has a version reference, it shall be possible to identify this at access level 2 or 3.

14.6 Monitoring of memory contents

The contents of the memories containing the site specific data shall be automatically checked at intervals not exceeding 1 h. The checking device shall signal a system fault if a corruption of the memory contents is detected.

Compliance Signature

Praesideo is compliant.

All Praesideo programs (executable code and data) are stored in Flash EEPROM.

Firmware (i.e. the program) can be replaced using the File Transfer Application. Using the File Transfer Application requires access level 4.

The version of the firmware of the units that have an LCD (access level 3) is visible on the units and on the firmware upgrade web page (that can be accessed via the web interface of the network controller). The version of the network controller software is visible on the network controller display and the web start page. Getting access to the web interface of the network controller requires access level 3.

Alteration of site specific data can only be done via the web pages offered by the web interface of the network controller (configuration data) and via the File Transfer Application (message sets). Getting access to the web interface of the network controller requires access level 3. Using the File Transfer Application requires access level 4.

Configuration of the Praesideo system is implemented to be data-driven and is not part of the program executable. Also transferring message sets to the Praesideo system is data-driven and is not part of the program executable. Therefore alteration of the site specific data does not affect the structure of the program.

Site specific data is stored in a Flash EEPROM based file system. The file system is maintained by the VxWorks Flash file system manager using a dedicated cyclic Flash-Write program mechanism.

Site specific data can be viewed and maintained from the configuration web interface. Using the web interface requires access level 3.

The site specific data of the Praesideo system does not have a version reference.

Praesideo is compliant.

The message store is checked every 100 s using checksum validation. Upon detecting corruption, a fault is reported indicating a corrupt message store.

The configuration file is checked at intervals not exceeding 1 h using checksum validation. Upon detecting corruption, a fault is reported indicating a corrupt configuration.
