求翻译：用PLC进行模拟量控制的好处是，在进行模拟量控制的同时，开关量也可控制。这个优点是别的控制器所不具备的，或控制的实现不如PLC方便。 当然，若纯为模拟量的系统，用PLC可能在性能价格比上不如用调节器。这也是应当看到的。是什么意思？

Use PLC for analog control of the benefit is that, in an analog control of the switch, volume control is also available. Another advantage is that the controller does not have control of, or less than the realization PLC easy. Of course, if it is purely for the simulation of the system, and may be u

PLC analog control benefits, while the analog control, switch can also be controlled. The advantages of other controllers do not have, or easy to control than the implementation of PLC. Of course, if solely for analog systems, PLC may use conditioner on the performance-cost ratio. This should be see

Carries on the simulation quantity control with PLC the advantage is, while carries on the simulation quantity control, the switch quantity also may control.This merit is other controller does not have, or the control realization was inferior PLC is convenient. Certainly, if for the simulation quant
