| Objective To automatically control the large centrifuge. Methods A centrifuge control system of upper and lower computer was designed composed of the upper computer and the PLC. The upper computer communicated with the PLC by Enternet and OPC, and the PLC communicated with a digital DC drive by DeviceNet. The PLC program and the control software of the host computer were developed based on Delphi. Results Intended functions of the hardware and software were achieved, the system automatically controlled the large centrifuge. Conclusion The centrifuge control system had good performances and high reliability, and was simply to handle. |
