Abstract—PLC (Programmable Logic Controller) is a type of electric control device, as compared with the traditional control devices, it has many advantages, so PLC is used in industy widely. Vertigo is an illusion of motion, as the surrounding environment or its rotation, or swing instability, shaking, top-heavy sense. The clinical manifestation is the uncontrolled eyes nystagmus. Based on the symptoms, we can assess the presence of disease by eye movements of people in different positions.
This paper focuses on the design and realization of control system based on PLC vertigo disease diagnosis, the whole system includes rotating equipment and PC. Rotating equipment mainly includes electrical equipment, mechanical equipment, PLC, etc. The PC part is the software part, including the PLC program, PLC interface program and the main control program. Proved by the experiment, the control equipment has met the predetermined technical requirements. Achieving the requirements of clockwise rotation, counter clockwise rotation, continuous rotation, rotation of single or several rings. Compared with other similar diagnostic equipment, the operation is simple safe and reliable. The patient is positioned accurate, so the diagnosis process is rigorous, providing the reliable diagnostic basis for diagnosis of vertigo disease.

Index Terms—PLC, diagnosis of vertigo, rotation, communication.
