3.
If you also change the project on the memory card, i.e. then want to reload the
configuration:
–
Select the "Reset to factory settings" area in the opened online and diagnostics view.
–
Activate the option "Delete password to protect confidential PLC configuration data".
To avoid a repeated start-up of the CPU, also select the "Format memory card" option.
–
Then load the project with the changed configuration and the desired password.
4.
If you do not have to change the project on the memory card, i.e. only the wrong password
is set:
–
In the Online and diagnostics view, you specify the area "Password for the protection of
confidential PLC configuration data".
–
Click the "Delete" button. If the "Delete" button is not available, no password has been
set in the CPU yet.
–
Enter the required password and click the "Set" button.
If the correct password has been entered, the CPU can use the protected PLC configuration
data.
No write access to the CPU
If you do not have write access to the load memory (read access level), remove the memory
card from the CPU or delete the memory card externally, e.g. in your computer, before you
reset to factory settings with the option "Delete password to protect confidential PLC
configuration data".
Note
Reset to factory settings with mode selector of the CPU
Restoring the factory settings of the CPU via the mode selector also deletes the IP address of
the CPU, but not the password for protecting confidential PLC configuration data.
