Control scale mainly refers to the number of input and output points of control switch quantity and analog input and output, or both (closed circuit system). However, it is mainly measured by switching value. The circuit number of analog quantity can be converted into the point of switching quantity, and approximately one circuit is equivalent to 8~16 points.

According to this number of points, PLC can be roughly divided into microcomputers, minicomputers, medium-size computers, mainframe computers and ultra-large computers.

There are only dozens of microcomputer control points, for example, the V80 series PLC body of Devon Company is from 16 to 40, the CPM1A series PLC of OMRON Company and the logo of Siemens are only 10.

The control points of minicomputer can reach more than 100. For example, the V80 series PLC of Davidson can be expanded to 256 points, the C60P of OMRON can reach 148 points, and the CQM1 can reach 256 points. The S7-200 of Siemens in Germany can reach 64 points.

The number of control points for medium-sized computers can reach nearly 500, even 1000. For example, Davidson’s PPC11 series can be expanded to 1024 points, OMRON’s C200H machine can be normally configured to more than 700 points, and C200Ha machine can be configured to more than 1000 points. The S7300 of Siemens in Germany can reach 512 points at most.

Mainframe: The number of control points is generally more than 1000. For example, the PPC22 series of Davidson can be expanded to 2048 points, and the C1000H and CV1000 of OMRON can be configured to 1024 points locally. The local configuration of C2000H and CV2000 can reach 2048 points.

Ultramainframe: control points can reach tens of thousands, even tens of thousands. For example, the 90-70 units of GE can have 24000 points and 8000 analog channels. Another example is the PC-E984-785 machine of American Modicon Company. The total number of switch gauges is 32k (32768), and the analog quantity is 2048. Siemens SS-115U-CPU945 has a total number of switching points of 8k, and there can also be 512 analog signals. wait.

The above division is not strict, but only approximate, and is intended to facilitate the configuration and use of the system.

Generally speaking, according to the actual I/O points, those falling in the above different ranges must choose the corresponding model, and the performance-price ratio must be higher; On the contrary, it must be worse.

Naturally, there are also special circumstances. For example, the number of control points is not very large, and it is not necessary to use the mainframe. However, due to the large number of special control units of the mainframe, it can be configured for hot standby, so the mainframe is used.
