4.20.3 Protection
Protection functions
The module provides various access levels to restrict access to certain functions.
NOTICE
Configuring an access level does not replace the know-how protection
Configuring access levels prevents unauthorized changes to the module by restricting the
download rights.
This does not, however, provide write or read protection for blocks on a memory card. Use
the know-how protection to protect the code of blocks on the memory card.
The table of access levels
You configure the access levels in the table. The green check mark in the columns on the
right of the particular access level indicate the maximum possible operations without
knowing the password for this access level.
The default access level is "Full access (no protection)". Every user can read and modify the
configuration. No password has been configured and no password is required for online
access.
