UBC717AE01 HIEE300927R0101 ABB1.2. Definition and selection of PLC: PLCOPEN defines PLC as: a solid-state control system with programming ability. The main function of PLC is to realize various types of control functions required by users after programming. , we have to use a lot of dedicated circuits or relay groups to complete

into a control function. Now PLC is widely used in almost all industries, and most of the products around us are manufactured by PLC-controlled equipment. For example, plastics, packaging, paper,, petrochemicals, elevators, bars, ceramics and so on. .Because of the different control methods, they were divided into process control and sequential control or discrete control in the past. The process control originated from the early process instrument control, and then gradually developed into DCS, while the sequential control originated from the early relay group. PLC has been developed, but with the development of microelectronic software, hardware and communication technology, many DCS and PLC currently use the same or similar technology platform, the difference between the two is getting smaller and smaller, and most new-generation control systems There is no longer a distinction between DCS and PLC, but whether the new-generation controller is called PLC or DCS or FCS, PAC, NCS has not been recognized by the majority of manufacturers. Especially the development of network and field bus makes DCS more and more worthless to exist alone. Many large companies have combined the functions of DCS, PLC, IPC and FCS into the new generation control system. In order to simplify various concepts, we divide the application of PLC into engineering and OEM according to the size of the project and the repetition of the project. The engineering mainly refers to the automation system with obvious characteristics of the papermaking, petrochemical, cement, large-scale port machinery and other projects. And OEM mainly refers to various equipment using PLC, such as elevators, extruders, packaging machines, reflow soldering, dispensing machines, special vehicles, etc. “These two big parts constitute the main market of PLC. There are indeed many uses Single-chip microcomputers, such as indoor air conditioner controllers, TV controllers, microwave oven controllers, etc., some of which have quite complex functions. Then why is there a need for PLC? There are indeed many systems that use single-chip microcomputers, such as Indoor air conditioner controllers, TV controllers, microwave oven controllers, etc., some of which have quite complex functions. Then why is there a need for PLC? All control options are based on two factors: performance and cost. Considering the aspect, that is, the price ratio. This is like buying a house. We can build a house with sand, or we can buy a ready-made commercial house. If we build a house by ourselves, we not only need civil engineering, we also need water, gas, electricity, sewage, etc. Auxiliary functions, and we only need to decorate it when we buy a commercial house.
