IOP304 Metso METSO Controller, The control signal of 0～10V is output by the analog output function module of the PLC to control the output frequency of the FR-E540 frequency converter. The frequency converter controls the speed of the three-phase asynchronous motor in real time. The motor drives the paddle of the wave maker to strike the water surface. Different motor speeds result in different wave distances and wave peaks between two wave heads. Thus, different speeds of the three-phase asynchronous motor correspond to different wave heads, wave distances, and wave peaks. Therefore, different speed combinations of two three-phase asynchronous motors can simulate different sea conditions in real time. The current generation system is also controlled by a combination of AnSH PLC and FX2N PLC to operate their respective power water pumps, creating different water flow energies. The wind generation system is controlled by AnSH PLC to operate high-power fans. It is essential to use PLC control in situations where the control system logic is complex (requiring a large number of intermediate relays, time relays, counters, etc.), process flows and product modifications are frequent, data processing and information management are needed (including data operations, analog control, PID regulation, etc.), the system requires high reliability and stability, and factory automation networking is planned.
