  • Windows based – drag and drop

XML based Process graphics builder, enabled for Web based graphic

Engineering and Database Maintenance

Process Operations

Operator Interface

  • Consistent operation from displays

    • Touch and feel

Single and Multi-screen Operator Stations

One Alarm screen for all equipment

Process Operation Security

  • Integration of Operator Effectiveness Tools

    • Alarm management

    • Asset management

Web based Process displays

Safe & Secure view of the process

Integration of Video

Process Operations

Asset Maintenance

  • All Equipment information sources are integrated

    • Hart / FF for information and monitoring

    • Sensor calibration

    • On-line documents

    • Interface to Computer Maintenance Management Systems - Maximo, SAP

Diagnosis of valves

Applies to all valves, not just smart ones

Diagnoses the entire loop, not just the valve

Asset Management

Detection of equipment failure and maintenance

recommendations to prevent unplanned plant shutdown
