Configuring know-how protection

Before activating the know-how protection, enter the parameters in this exception list that are

permitted to remain readable and writable for the end user despite the know-how protection.

The exception list can only be created via the expert list. The exception list has no influence on

the input screen forms in STARTER.

In the factory setting, the exception list only includes the password for know-how protection.

You do not need to change the exception list, if, with exception of the password, you do not

require additional adjustable parameters in the exception list.

Factory setting for the exception list:

● p7763 = 1 (exception list contains precisely one parameter)

● p7764[0] = 7766 (parameter number for entering the password)

Parameters belonging to the exception list can be viewed everywhere

All parameters in the exception list can be viewed in the web server and other commissioning

tools, even when know-how protection is activated.

Therefore, make sure that no critical parameters are entered in the exception list.

Absolute know-how protection

If you remove password p7766 from the exception list, it is no longer possible to enter or change

the password for know-how protection.
