Business Process and Level 3 Systems

In larger installations, there exists a need to coordinate the entire complex from a single computer.  This higher Level function serves to interface the Level 2 systems to the "outside" world and often contains high-level process information.  Typical examples of a Level 3 application are:

• Generate mill lineup from a Level 6 plant wide scheduling computer
• Keep process and quality standards at the mill level
• Retain process and business information on a long term basis
• Relational database of all collected process variables
• Retain, summarize and send process data to Level 6
• Send necessary information to accounting systems
• Retain maintenance records and spare parts
• Coordinate material between the hot mill and coil process line
• Coordinate with hot mill shipping
