In general, the stage machine control device is for controlling various lighting, sound equipment, event equipment, and stage machinery installed on the stage of a performance facility, and most of the stage machinery equipment is provided using a console in which a large number of switch devices are arranged. Is controlling.

The type of stage machinery controller that has been used up to now is a pure analog method that uses a combination of a relay and magnetic contactor for more than 20 years, and in recent years, PLC (Power Line Communication) used in F / A (factory automation) ) Can be distinguished semi-digitally using a proper combination, and there are foreign systems recently imported from foreign countries.

In the analog method, one part is attached and wired one by one, and the control switch and driving device (consisting of relay and magnet) are connected with their respective wires to operate. The complicated process of fastening the screws to the parts is a situation that is holding a lot of material and labor costs.

In addition, given the reality of today, such as a large theater requiring position control and speed control in a simple system that simply lifts up the stage machinery (forwards and reverses the motor), it is time to solve this analog system. Is already long gone, and it is nominally digital PLC system that solved this problem.

But in fact, even this PLC system is not a complete digital system, but rather a PLC added to an existing analog system.

As the system has already been verified for its functionality in the F / A market, it shows satisfactory performance in today's complex and diverse systems, but it is causing an increase in wiring materials and labor costs by adding PLCs to analog methods. In addition, the time required to program a PLC and the associated labor costs have increased.

In addition, it is used for relatively large stage machinery control at a high price, but it is difficult to apply in terms of price to the control of small and medium stage machinery such as auditorium or small / small theater, and the space occupied by the equipment is greatly increased.
