Defining security
levels
Recipe directories that were created in the HMI-Builder programming software cannot
be deleted in run mode.
This function can be used to create a security system for the machine. Operators can
be assigned user-specific authorizations for the system.
A security level can be assigned to the following objects:
Blocks
Function keys
Touch keys
Maneuverable objects
Each security level is protected by a password. To gain access to the individual levels,
the user must register with a password for the currrent level or a higher security level.
This function is optional.
When the input is activated you define a security level (0-8) in the dialog for the relevant
object via the [Access] tab. Security level 0 means all users can access the object. In
this case, you will not be prompted for a password.
