Level 2
Level 2 will include the operator interaction to process plant (its control) through dedicated
Human Machine Interfaces (HMI) located in the control room. The control Network will be
based on Ethernet/IP. Level 0 through 2 will be what is commonly referred to as the Process
Control System (PCS). Level 2 will also provide means of data acquisition and archiving.
Level 3
Level 3 refers to the operational systems that will be used throughout the facility.
Due to the nature of the proposed TSF, these systems will not be limited to those required only
for process operations, but will also include all operational systems used across the entire
facility. The data historian will be used to collect data throughout the facility, which will be
provided in the Level 3 systems. The following provides a summary list of the Level 3
operational systems for the proposed TSF:
Level 4
Data Historian.
Environmental Monitoring and Reporting.
Production Management and Reporting.
Water, Wastewater Monitoring and Reporting.
Fuel and Consumables Management and Reporting.
Laboratory Information Management.
Alarm and Event Management and Reporting.
Level 4 refers to the Business Systems Layer. The Business Systems Layer falls under the
responsibility of BGNA. The proposed TSF will incorporate BGNA’s well-established Business
Systems Layer into the proposed TSF’s process controls.
For effective and safe operation of the proposed TSF, specific systems in the Business Layer will
be integrated with the proposed TSF’s Level 3 systems. Integration between Level 3 and Level 4
systems will be focused on systems related to Supply Chain Management (logistics and materials
management) and Maintenance.
The Systems Network Architecture is illustrated by the diagram included in Appendix 1-A
(H340940-0000-75-004-0009). The architecture depicts the Process Control Network (Level 0,
1, and 2), the Production & Process Network (Level 3), and the Information Technologies,
Business and North America Regional Business Unit (NARBU) network (Level 4).
