3.7 Releasing the Password
The Release Password option only appears if you have defined a password for the
TD 200.
The Release Password option allows the operator to end or pause an editing
session and to return the TD 200 to password protection. The password must then
be reentered before any editing is allowed.
The TD 200 also has a 2-minute time-out feature which automatically releases the
password, thereby restoring password protection. If the keypad is inactive (no keys
are pressed) for 2 minutes, the TD 200 prompts the operator to enter the password
again before editing.
Note
The Release Password option affects only the password protection offered by the
TD 200, which restricts the editing of data values that are embedded in a
message. The Release Password option is set in the parameter block for the TD
200. The Release Password option does not affect the CPU password that
restricts the editing of a user program running on an S7-200 CPU.
Restoring the Password Protection
Once you have finished editing, use the following procedure to end your editing
session and restore the password protection for modifying variables (you must
then reenter the password to make any additional changes):
