TOYO PETRONET LNG, DAHEJ. MicroSCADA Based MMI System FUNCTION DESCRIPTION 3.2.6
User Authorisation
The application software provides an application framework upon which the customer application can be built. This framework includes an authorization mechanism with four authorization levels. These levels are: View Level: Users belonging to this group are allowed to view the application. They are not allowed to make Engineering operations or to use programming tools. Engineering Level: All rights are granted, excluding user management. System Management Level: System manager, all rights granted, including the rights to add and remove users. The MMI system shall have two levels of password protection ;one read only and other for authorization for modifying relay settings etc. The authorization mechanism restricts the use of the system in the following way: •
Only one active user at a time may be assigned to each monitor of the system.
•
The authorization level is zeroed automatically when 8 hours have elapsed from last log-in.
•
The system manager adds and removes users from the system using a tool picture called Change Password in the Accessories menu.
•
All users log in to the system by entering a password in the start-up picture.
•
A new user has no password. At first log-in he types his name and presses Enter for the password. Then he chooses his own password and enters it with the Change Password tool in the accessories menu.
•
Only the user himself may change his password.
The MicroSCADA system keeps a record of the users allowed to log into the system. This record is automatically edited when the system manager adds or removes users. The record can be read and printed out, but it can be edited only in the manner described above. The user authorization level together with the user name is used, for instance, in supervisory pictures to prevent unauthorized operations and in printouts as an identifier. For the present application, one user will be provided for each of the authorization levels i.e. View, Engineering and System Management.

3.2.9
Documentation
MicroSCADA system is equipped with automatic on-line documentation functions for documenting the application. Documentation can be produced totally or selectively. Documents are stored on the hard disk under a user given name and can be printed out. A complete document covers all the details of the application. The documents have a predefined layout. Documentation is produced from the tool picture by means of which the user defines the subject matter that will be documented. Documentation covers the following items: •
Pictures
•
Library representations
•
Process objects etc.
3.2.10 Communication System The base system uses a communication system called PC-NET, which is installed in the base system computer. PC-NET stands for communication software, which runs on the main processor of a Windows 2000 computer in parallel with the base system. The task of PC-NET is to convert the external protocols used for communicating with process units such as relays to the ACP protocol, which is used between PC-NET and the MicroSCADA base system. As communication channels, the PC-NET software utilises the serial line COM ports of the PC.

TOYO PETRONET LNG, DAHEJ. MicroSCADA Based MMI System FUNCTION DESCRIPTION 3.2.6
User Authorisation
The application software provides an application framework upon which the customer application can be built. This framework includes an authorization mechanism with four authorization levels. These levels are: View Level: Users belonging to this group are allowed to view the application. They are not allowed to make Engineering operations or to use programming tools. Engineering Level: All rights are granted, excluding user management. System Management Level: System manager, all rights granted, including the rights to add and remove users. The MMI system shall have two levels of password protection ;one read only and other for authorization for modifying relay settings etc. The authorization mechanism restricts the use of the system in the following way: •
Only one active user at a time may be assigned to each monitor of the system.
•
The authorization level is zeroed automatically when 8 hours have elapsed from last log-in.
•
The system manager adds and removes users from the system using a tool picture called Change Password in the Accessories menu.
•
All users log in to the system by entering a password in the start-up picture.
•
A new user has no password. At first log-in he types his name and presses Enter for the password. Then he chooses his own password and enters it with the Change Password tool in the accessories menu.
•
Only the user himself may change his password.
The MicroSCADA system keeps a record of the users allowed to log into the system. This record is automatically edited when the system manager adds or removes users. The record can be read and printed out, but it can be edited only in the manner described above. The user authorization level together with the user name is used, for instance, in supervisory pictures to prevent unauthorized operations and in printouts as an identifier. For the present application, one user will be provided for each of the authorization levels i.e. View, Engineering and System Management.

3.2.9
Documentation
MicroSCADA system is equipped with automatic on-line documentation functions for documenting the application. Documentation can be produced totally or selectively. Documents are stored on the hard disk under a user given name and can be printed out. A complete document covers all the details of the application. The documents have a predefined layout. Documentation is produced from the tool picture by means of which the user defines the subject matter that will be documented. Documentation covers the following items: •
Pictures
•
Library representations
•
Process objects etc.
3.2.10 Communication System The base system uses a communication system called PC-NET, which is installed in the base system computer. PC-NET stands for communication software, which runs on the main processor of a Windows 2000 computer in parallel with the base system. The task of PC-NET is to convert the external protocols used for communicating with process units such as relays to the ACP protocol, which is used between PC-NET and the MicroSCADA base system. As communication channels, the PC-NET software utilises the serial line COM ports of the PC.
