Factory Information System(s) [FIS]

Components of Factory Information System(s).
1. Reliable, Uniform and Reusable data source component. FIS Driver (16-bit) for PLC. Metering data model. 
2. FIS Driver (16-bit) full system integration, including synchronization mechanism for driver's meters.
3. Typical trend (8 Hrs. Shift History/Realtime) data output based on FIS driver.
4. Extension to Metering, event-driven Root Fault priority logic and analysis. This probably the most valuable information that can be available. Addresses both Reactive and Proactive areas. In contrast to a standard KPIs this one is specific(custom) in each case/machine.
