Protecting Presets From Being Overwritten - HEIDENHAIN TNC 620 User Manual

Protecting presets from being overwritten

You can use the LOCKED column to protect any lines in the preset
table from being overwritten. The write-protected lines are color-
highlighted in the preset table.
If you want to overwrite a write-protected line with a manual touch
probe cycle, confirm with OK and enter the password (where
password-protected).
Caution: Data may be lost!
Lines that were locked with the LOCK / UNLOCK PASSWORD
function can be unlocked only with the selected password.
Forgotten passwords cannot be reset. This means that locked
lines would be locked permanently. The preset table would thus
no longer be fully usable.
Prefer the alternative LOCK / UNLOCK function
Note down your passwords
Proceed as follows to protect a preset from being overwritten:
Press the CHANGE PRESET soft key
Select the LOCKED column
Press the EDIT CURRENT FIELD soft key
Protection for a preset without using a password:
Press the LOCK / UNLOCK soft key
The control writes an L in the LOCKED column.
Use a password to protect a preset:
Press the LOCK / UNLOCK PASSWORD soft key
Enter the password in the pop-up window
Confirm with the OK soft key or with the ENT key:
The control writes ### in the LOCKED column.
