The client's building relied on several large back-up generators to provide power to the building in the event of an emergency until power from the grid is restored. DMC programmed the fuel pumping system that feeds each generator, automating the monitoring and transfer of diesel fuel in long-term storage tanks to smaller tanks for immediate use.
The solution utilized several hardware-redundant Automation Direct DL305 PLCs for a distributed control system. System status and local control was available through local HMIs present throughout the distributed control system.
