      Control System Flow Chart

       

    • Direct Control

      • Full programmable logic controller (PLC) system
      • PLC I/O modules directly connected to equipment and instrumentation
      • PLC CPU can be connected to any BAS via open protocol networks to exchange data for trending, M&V, and remote UI
      • Best suited for:
        • facilities with no effective central plant control system
        • plants without data control systems
        • installations which would require significant updates to the existing BAS
    • Supervisory Control

      • CEO® CPU only, no physical I/O modules
      • CEO® connected to any BAS via open protocol networks
      • BAS I/O modules directly connected to equipment and instrumentation
      • BAS writes equipment status and process signals to CEO®
      • CEO® adaptive algorithms determine equipment operation to minimize kW/ton and write values to BAS
      • BAS executes physical control instruction
      • Built-in bumpless transfer and communication watchdog
      • Best suited for:
        • facilities with functional control system but no energy optimization capability
        • operations sensitive to any disruption
