to lock the device software to ensure that parameters cannot be changed. Non-safety-related
parameters remain unchanged.
NOTICE
Once the SIL device has been locked, the process-related parameters are write protected,
and thereby locked, for security reasons.
It is still possible to read the parameters. When SIL locking is enabled, restrictions apply on all
communication options, such as the service interface, HART protocol and WirelessHART
protocol, local display and WLAN.
‣
Follow the specified locking sequence.
1. Ensure preconditions are met.
