Security Considerations
The 990 SmartRadar FlexLine provides several features designed to
prevent accidental changes to the device configuration or calibration
data.
These features include:
Configuration Lock protection of HART SmartView local
commissioning tool and display
Configuration Lock protection for every communication interface
Hardware W&M write protect jumper / switch per FlexConn board
Hardware full configuration write protect jumper / switch per FlexConn
board
Hardware Configuration Lock read protect jumper / switch
Software W&M write protect seal
A hardware write-protect jumper / switches locks out W&M / all
changes regardless of the entry of a Configuration Lock. The
hardware jumper requires physical access to the device as well as
partial disassembly and should not be modified where the electronics
are exposed to harsh conditions or where unsafe conditions exist.
For W&M configuration changes without changing the W&M hardware
jumper position the accredited service engineer or notified body
representative may choose to rely on the software W&M write protect
seal.
Security note 1
During commissioning the hardware full configuration write protect
jumper / switch for each FlexConn board should be placed so no
unintended or accidental configuration changes will be possible.
For security and unintended changes by people that are not allowed
making changes the "Protect all configuration jumper" must be placed
on all boards after device commissioning and a physical seal shall be
applied to the outsight of the device.
Put the "Protect all configuration entities" jumper of all relevant boards
so no external resource can modify anything of the configuration
(operational settings) of the 990 SmartRadar FlexLine.
