Upgrade to a PLC based Control System to replace the old style electro-mechanical relay controls. In addition to saving space and increasing system reliability, a PLC offers features such as remote communication, diagnostic capability and the ability to interface with the plant DCS system. It is proven that a PLC based control system is more economical than a DCS based control system for coal yard operation.

• A new HMI Operator Station will give operations a central location for monitoring and controlling yard operations. Remote MMI Stations can also be encorporated giving plant personnel viewing access (but not control) from multiple locations within the yard. Maintenance can use the same MMI stations to help troubleshoot and pinpoint the exact location of a problem. This will drastically reduce the time abd duration of a repair.
  
  
• By replacing chain driven gearboxes with direct drive motor/gearbox assembly, increased reliability of the conveyor system will be realized. In addition, no time will be spent repairing, replacing and greasing the drive chain. The current sensors on the new motor will enable the operators to monitor motor amp draw and prevent an unexpected motor failure.
  
  
• We can design and upgrade a new Warning and Safety System including Warning Lights and Horns, Belt Alignment Switches and Pull Cords.
  
  
• By using Fiber Optic Communications and Radio Modems, all of the coal yard operations andmonitoring can be centrally located. This could include every process from where coal enters the plant tothe bunker filling operations.
