The S7-1516 PLC was chosen to control the Cooling Water System because it provided a familiar and intuitive programming environment through TIA Portal and because it offered some key features that made for quick assembly, commissioning and maintenance. In addition, the G120 AC drives were easily configured using StartDrive integrated into TIA Portal. Finally, the Comfort Panel provided a robust and highly responsive HMI that was easy to program and quickly provided the operator with critical pump and system data.
