4.8. User management
Via the user management, logic diagrams can be locked against unintentional or unauthorised
changes. The access to function blocks in the current logic plan can be deenabled or enabled. This
means, that in a disabled logic diagram all menu options and toolbars for adding function blocks
are grey (= disnabled). Furthermore, in function blocks that have already been added, the
parameters can’t be changed any more.
For unlocking, a password is necessary. In this case, the configured values and the functional
modules of a disabled diagram can be displayed but they cannot be modified. This function
ensures that unauthorized persons can’t modify the logic diagram.
NOTICE:
Logic diagrams can only be unlocked with the password that has also been used to deactivate the
logic diagram. A disabled logic diagram can no longer be compiled. However, access to the
SCUxxx module is still possible.
