Background
          A steel plant was producing usable fuel gas for their processes. The project involved:
          
          
                - Gas mixing plant automation in the steel line
- All solenoid valves integration in the system
- Ratio parameter logic - for mixing ratio parameters
- Gas mixing logic - proper proportion of mix gas
- Development of screens
          
Implementation
          
                - Simatic Manager 5.5 , WinCC SCADA V7.2 (CPU 400H System)
- I/O counts: 200 Plus
- Customized block and faceplate to meet customer requirements
- Communication between Engineering Station(ES) and Operating Station(OS) through Ethernet
Outcome
          
                - Reduction in manpower and operation cost due to centralized operation
- Reduction in maintenance time and cost 
- Data of all parameters logged with limits
