PLC for process control, has been a trend. Because the use of PLC to achieve this control, the price is lower than the use of other, and, when using it, in the analog control at the same time, it can be very convenient to carry out other controls. Plus all kinds of processes
The development and application of control modules, as well as the introduction and use of related software, it has become very easy to use PLC to carry out various process control, and its programming is also very simple. Therefore, at present, the share of PLC used by some manufacturers for analog quantity control has exceeded that used for Sequence control.
3. For motion control
Motion control mainly refers to the control of the position, speed and acceleration of the working object. Can be a single coordinate, that is, the control object to move in a straight line; It is also multi-coordinate, controlling the plane, three-dimensional, and degree transformation of the object.
The numerical control technology, referred to as numerical control (NC), which was born in the United States in the 1950s, is based on the application of electronic computers and this pulse quantity and continues to develop and improve the motion control technology. Now, it has developed to a perfect situation, has become
An important pillar of today’s automation technology.
PLC also has the ability to handle pulse volume. The PLC has a pulse signal input point or module, which can receive pulse quantity input (PI). PLC has pulse signal output point or module, which can output pulse quantity (PO). You have two kinds of work, PI/PO.
Using PLC to achieve this control, the price is much lower than using NC. Moreover, it can also carry out other controls while carrying out motion control. In addition, the development and application of various motion control modules of PLC, as well as the launch and implementation of related software
With PLC for all kinds of motion control has become very easy, its programming can also use NC language, very simple.
In recent years, there has also been the first PLC for MOTION control, that is, P (PROGRAMMABLE) M (MOTION) C (CONTROLLER), programmable motion controller, referred to as PMC.
Large, controlled coordinates multi-operation convenient motion control provides a good platform. Therefore, the use of PLC motion control, to a considerable extent, can replace the price of its expensive numerical control system.
