There are many types of programmable controllers, which can be classified from different perspectives:
By control scale
The control scale mainly refers to the number of input and output points of control switching value and analog input and output, or both (closed circuit system). However, it is mainly measured by switching value. The number of analog channels can be converted into switching points, roughly equivalent to 8-16 points.
According to this point, PLC can be roughly divided into microcomputer, minicomputer, medium-sized computer, mainframe and super mainframe.
There are only dozens of microcomputer control points, including the CPM1A series PLC of OMRON Company, and the logo of Siemens is only 10 points.
Small computer control points can reach more than 100 points. For example, OMRON’s C60P can reach 148 points and CQM1 can reach 256 points. The S7-200 machine of Siemens in Germany can reach 64 points.
The control points of medium-sized computers can reach nearly 500 points, even thousands. For example, the common configuration of OMRON C200H can reach more than 700 points, and the C200Ha can reach more than 1000 points. Siemens S7300 can reach 512 points at most.
Mainframe: The number of control points is generally above 1000. For example, the C1000H and CV1000 of OMRON can be configured locally up to 1024 points. The local configuration of C2000H and CV2000 can reach 2048 points.
Super mainframe: the number of control points can reach tens of thousands, even tens of thousands. For example, the 90-70 computer of GE Company in the United States has 24000 points, and 8000 analog channels. Another example is the PC-E984-785 machine of Modicon, which has a total of 32k (32768) switch gauges and 2048 analog channels. Siemens SS-115U-CPU945 has a total switching value of 8k and 512 analog channels. wait.
The above division is not strict, but only rough, for the purpose of facilitating the configuration and use of the system.
Generally speaking, according to the actual I/O points, if the machine falls into the above different ranges, the performance price ratio will be higher if the corresponding model is selected; On the contrary, it must be worse.
Naturally, there are also special circumstances. If the number of control points is not very large, it is not necessary to use the mainframe. However, because of the large number of special control units of the mainframe, hot standby configuration can be carried out, so the mainframe is used.
