Siemens brand as the most authoritative use of modules, has been in the major areas of our country have a very wide range of applications. Even if it is recovered Siemens modules can be reused, to maximize the value. But in fact, according to its size and performance can be controlled it can be divided into several different grades.
First, minicomputer
Control points are usually small size within the machine 256, the control is suitable for a small stand-alone system or control system, the effect of saying similar size, its processing speed of between 0.8 to 1.3 seconds, and storage reaches the 2k, from a professional point of view, to achieve this level, even small machines have also been very good.
This is all the control functions and computing power inside, which belong to the most basic, so work on the speed of calculation is the lowest, the same number of templates and template input output of less than.
Second, the medium-sized machine
In general, the number of medium-sized machine control point will not be greater than 2048, it is precisely because of this feature, it can directly control the device. More powerful is that it can simultaneously perform a plurality of programmable controllers monitoring, that is to say it is more suitable for large control systems, of course, it is also medium-sized control system is capable of controlling. In life, this medium-sized machine number on the use of the most widely used, because it is sort of a small physique, it is relatively easy to operate, more importantly, it applies to a wider range, so the actual industrial production has not kind of meaning.
This type of programmable controller has a very strong function of the control and computing power, it is generally difficult to live logic operation thereof, and some complex trigonometric functions, including complex exponential operations are able to complete all. In the current market, the recovery module Siemens medium-sized machine is the most popular, and most popular.
Third, the mainframe
Mainframe control point also not be greater than 2048, but it is only able to complete a variety of complex arithmetic operations, even more importantly, complicated matrix operations it may be qualified. As it can direct control of the device as medium-sized machine, the controller can also monitor the next stage. It is currently processing speed reached the point 0.3 m 1000 words per second. So this speed is another domestic machinery and equipment are unmatched.
Since it is a mainframe, also known as a high-end machine, and that it has control functions and computing power is naturally Needless to say, do not doubt that, in addition to a variety of common logic operations, complex trigonometric, exponential, and even complex matrix operations can not stumped by it. Its output is input to imitate very comprehensive work rate is extremely high. Control tasks can be completed in a perfect state of large-scale cases, this template is usually used as a master in a networked among.
In fact, in addition to these types, it can be combined in different ways to divide into several, took stacked manner, the overall structure is very compact, resulting in its very small volume, so it is easy to install . But the people most like about it is that it the flexibility to mix and set all the advantages in one, using a combination of each of the different units which are able to form the core part of the installation process also allows flexible configuration, in accordance with this case, not a single module production industry will not like.
In summary, the recovery module Siemens actually not much demand, but face different models, distinguished in its size when we must clear rationale, or recover a high-end machine was used in the general situation on the inside overkill friends.
