Control and Safety Functions
The system has two computers: the control computer and the safety computer. The control computer is
responsible for the graphical user interface (GUI) and controls most of the hardware. The safety
computer is responsible for monitoring the safety system, including sensors. The control and safety
computers continually exchange information about pump speeds, centrifuge speeds, and motor and
valve positions to ensure safe operation through Ethernet and direct ribbon cable connection. Both
computers interface to gate arrays using their ISA buses.
Both computers calculate donor limits and available products. Independent tasks on both computers
ensure donor safety. The control computer is responsible for operator, procedure, and hardware control.
The safety computer ensures that the control computer is operating within the donor's safety
constraints. Figure 2-31 shows how the control and safety computers communicate via Ethernet. The
following functions are controlled/monitored by the control computer and monitored by the safety
computer:
•
Pumps
•
Centrifuge
•
Valves
•
Door sensors
•
Cassette position
