14.4 Know-how protection
You can use know-how protection to protect one or more blocks of the OB, FB, FC type and
global data blocks in your program from unauthorized access. You can enter a password in
order to restrict access to a block. The password protection prevents the block from being
read or changed without authorization.
Without the password only the following data concerning the block can be read:
● Block title, comments and block properties
● Block parameters (INPUT, OUTPUT, IN, OUT, RETURN)
● Call structure of the program
● Global tags without information on the point of use
Further actions that can be carried out with a know-how protected block:
● Copying and deleting
● Calling in a program
● Online/offline comparison
● Load
Setting up block know-how protection
1. Open the properties of the respective block.
2. Select the "Protection" option under "General".
