The above division is not strict, but only approximate, the purpose is to facilitate the configuration and use of the system.
Generally speaking, according to the actual number of I/O points, those who fall within the above different ranges should choose the corresponding model, and the performance-price ratio must be higher; on the contrary, it must be worse.
Naturally, there are special cases. If the number of control points is not too many, it is not necessary to use the mainframe, but because the mainframe has many special control units, it can be configured as a hot backup, so the mainframe is used.
Divide by structure
PLC can be divided into two categories: box type and modular type. Microcomputers and minicomputers are mostly box-type, but from the perspective of development trends, minicomputers have gradually developed into modular ones. Such as OMRON company, the original minicomputers are box type, and now the CQM1 is modular.
The PLC of the box integrates the power supply, CPU, memory, and I/O system into a small box. A host box is a complete PLC, which can be used for control. If the number of control points does not meet the requirements, an expansion cabinet can be connected, and a larger system is composed of the main cabinet and several expansion cabinets to realize the control of more points.
Modular PLC is divided into several modules according to functions, such as CPU module, input module, output module, power supply module and so on. The mainframe’s module functions are more single, so the types of modules are relatively more. This can also be said to be a trend. At present, the functions of some medium-sized machines tend to be single, and the types are also increasing. For example, in the same C20 series PLC of OMRON Company, the CPU unit of the H machine contains the power supply, while the Ha machine separates the power supply and has a separate power supply module.
The function of the module is more single and the variety is more, which can facilitate the system configuration, make the PLC better use, and achieve higher use efficiency.
There are three ways to link modules into a system:
No bottom plate, directly connected by the interface between modules, and then fixed to the corresponding guide rail. The V80 series PLC of Deweisen Company is this kind of structure, and it is relatively compact.
There is a base plate, and all modules are fixed on the base plate. Such as the PPC11, PPC22 and PPC31 series PLC of Deweisen Company, C200Ha machine of OMRON Company, CV2000 and other medium and large machines are this structure. It is relatively firm, but the number of slots on the bottom plate is fixed, such as 3, 5, 8, 10 slots and so on. The number of slots is not necessarily equal to the actual number of modules, and it is inevitable that there will be empty slots during configuration. This is not only wasteful, but also takes up more space, and it has to take up the unit to fill the excess slot.
Replace the bottom plate with a rack, and all modules are fixed on the rack. This structure is more complicated than the bottom plate type, but more reliable. This structure is mostly used by some extra-large PLCs.
