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):
