The old system was starting to fail and had to be replaced. A new Ethernet network was installed and new sensors and actuators were installed. The existing modbus communication with frequency drives and temperature sensors was included in the new system. A central ViewPort computer was installed in the engine control room, providing a graphical interface to the system.
