Problems solved by technology

[0003] However, the cost is high and the benefits are not obvious. If PLC control is used in the same equipment, fixtures, fixtures, and shielding boxes to achieve multi-functional coexistence requirements, the cost of the equipment will be greatly increased, and the space size of the equipment needs to be considered. Variety and difficulty of installation methods;
[0004] At present, the rapid replacement of electronic products has led to the rapid replacement of production equipment and test equipment, which are not available in the production process, so that there is a life cycle of 2 to 3 months. If PLC is used, it will undoubtedly increase the production cost of customers and Therefore, the use of PLC as the control of such equipment is not the best solution in the current market, and it also loses competitiveness due to cost issues.
At the same time, the input interface and output interface of PLC control are limited. For the automation system driven or controlled by multiple loads, multiple PLC controllers are required, which increases the cost of system automation control and is not conducive to centralized control.
