Each screen intuitively displays critical information for quick and easy operation. “Soft buttons” provide an intuitive “point and click” interface for navigating between screens, acknowledging alarms, and controlling equipment. SCADA/FLEX DISTRIBUTED CONTROL Overview SCADA/Flex Offers: • Process visualization (HMI) • Supervisory Control And Data Acquisition (SCADA) • Local or remote operating modes • Historical Trending • Alarming, alarm management and printing • Report Generation and Printing (Option ‘-R’) • High performance networking (Ethernet & Fiber Optic optional) • Interface to Fireye and Honeywell Flame Safeguards (optional) Quanta-Flame Flame Safeguards • Development Software allows continued development on site (Option ‘-DS’) Open Architecture for Third Party Applications (optional) SCADA/Flex can act as an OPC Server to any standard OPC Client. Alternatively, SCADA/Flex can act as an OPC Client to any standard OPC Server. SCADA/Flex leverages the ODBC Application Programming Interface (API), adding the capability to collect and write real-time secure electronic records to one or more relational databases. Data can easily be moved between a relational database and the SCADA/ Flex process database. Historical Trending Multi-colored strip charts display of any group of eight variables for any length of time. The Zoom feature and a data cursor allow precise readout and comparison of any event. Data may be placed on a server or flash drive for long- term storage and can be reloaded at any time for analysis. SCADA/Flex Workstation
