Use this function to enable write-protected parameters via local operation or an operating tool.
For local operation, the customer-specific access code defined in the Define access code
parameter is entered (® ä 154). If an incorrect access code is entered, the user retains his
current access authorization.
The write protection affects all parameters marked with the
local display, the symbol in front of a parameter indicates that the parameter is write-protected.
If no key is pressed for 10 minutes, or the user goes from the navigation and editing mode back to
the measured value display mode, the device automatically locks the write-protected parameters
after another 60 s .
