7.5 Write and know-how protection
Exceptions to write protection
Some functions are excluded from write protection, e.g.:
● Activating/deactivating write protection
● Changing the access level (p0003)
● Saving parameters (p0971)
● Safely removing the memory card (p9400)
● Restoring the factory setting
● Importing settings from an external data backup, e.g. upload from a memory card to the
converter.
The individual parameters that are excluded from the write protection, can be found in the
List Manual in Chapter "Parameters for write protection and protection of know-how".
Note
Write protection for multimaster fieldbus systems
When using multimaster fieldbus systems (e.g. CAN Bus, BACnet), parameters can be
changed in spite of an active write protection. So that write protection is also active when
accessing via these fieldbuses, you must additionally set p7762 to 1.
In STARTER, this setting is only possible via the expert list.
7.5.2
Know-how protection
Know-how protection
The know-how protection is used to encrypt configuring/engineering know-how, and protect it
against being changed or copied.
The settings of the converter are protected by a password.
If the password is lost, only default settings are possible.
The active know-how protection provides the following:
● All setting parameters are invisible.
● Parameters cannot be changed with a commissioning tool, e.g. operator panel or
STARTER.
● It is not possible to download the converter settings with the Starter or via a memory card
● It is not possible to use the trace function in the STARTER.
● Deleting the alarm history
● The STARTER dialog screens are disabled. The expert list in the STARTER contains
only display parameters.
In the case of active know-how protection, support by technical support personnel is only
possible with the consent of the machine manufacturer.
