In order to meet the requirements of the most difficult industrial automation applications, we have equipped the multichannel MultiCon CMC controllers with a new feature. The “MultiLevel Access" mode makes the MultiCon CMC even more universal. You can define up to 16 independent users including the administrator who is the only user with a permission to freely configure the device without any limitations. The administrator’s role also consists in defining permissions for other users. Only one user can be logged on at a given moment. The user is logged off after the lapse of time from the moment of the last interaction of the user with the device as specified by the administrator or upon express request of the user after clicking the padlock icon on the information bar. The authorisation process is additionally facilitated by the possibility of using USB keys. The hardware key allows the user to log on without the necessity of entering a password while removal of the key is equal to logging off. The key is assigned individually to each user. This facility will only be available for users whose devices have Access Dongle licence activated. Otherwise the login and logoff process must be carried out manually. The permission file may be saved using external memory and is therefore portable, which highly decreases the configuration time of subsequent units. The hardware key options are only available with a MultiCon CMC device with Access Dongle licence activated.
