Access Control
You can protect the VariSCR emission controller against unauthorized access by establishing the
access control in the MICT. The access control has four operating levels, three of which can be
secured with different PINs. As a default setting, the access control is not activated. If the access
control for the emission controller is activated, it is independent from the access levels that
control authorizations within the MICT.
Access Control
A user is logged in to the
Advanced Service
access level on the MICT. He
changes a configuration and would like to download the change to the
VariSCR emission controller. Although he has the full authorization set in
the MICT, he is prompted to log in with the PIN for the
Level 3 (Master)
. This
ensures that it is not possible for any user with an MICT and the generally
valid password to change the configuration of your emission controller.
Various functions are at your disposal on the four operating levels. The figure below illustrates
this:
