954 SmartServo FlexLine
2.10 Security Considerations
The 954 SmartServo 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.
A tamper detection feature is available for the CAN-SERVO (TII-SRV)
main control module of the 954 SmartServo FlexLine that can indicate
that an attempt was made to change either the configuration or
calibration of the device. This security features is designed to avoid
accidental changes and to provide a means to detect if an attempt was
made to change the configuration or upgrade the firmware when (W&M)
sealed and when the device is completely sealed.
