求翻译：作为一种产业控制电子装置，PLC若不能对这些量进行控制，那是一大不足。为此，各PLC厂家都在这方面进行大量的开发。目前，不仅大型、中型机可以进行模拟量控制，就是小型机，也能进行这样的控制。是什么意思？

Control electronics as an industry, plc, if not control of these quantities, it is a lack of To this end, the plc manufacturers a lot of development in this regard. At present, not only large and medium-sized machine can analog control. Is minicomputer, can such control.

As an industrial control electronics, PLC if it is not possible to control the volume, it is a major low. To this end, the PLC manufacturers are in a large number of the development. At present, not only large, medium-sized machines can be analog control, and that is small, and the control can be ca

As an industrial control electronics, PLC was unable to control the volume, that is a big enough. To this end, all PLC manufacturers are significant development in this regard. At present, large, medium-sized machine can not only for analog control, is the form factor, can also be controlled.

As one industrial control electronic installation, PLC if cannot carry on the control to these quantities, that is one big insufficient.Therefore, each PLC factory all carries on the massive developments in this aspect.At present, not only large-scale, the molding machine may carry on the simulation
