FX2N series PLC hardware

FX2N series PLC hardware and other types of PLC controller basic same, the main body consists of three parts, mainly including the central processor CPU, storage system and the input and output interface. The basic structure as shown in figure 1 - PLC 1. Some within the CPU module, power supply system also has a separate as a unit, programming unit generally as PLC peripherals. PLC internal use bus structure, transmission of data and instructions. External switch signal, analog signal and all kinds of sensor detection signal as the input variable of PLC, which is entered into the PLC input the input terminal of PLC memory, the collection and temporary controlled object of the actual operation status information and data; After the PLC internal operation and treatment, according to the actual movement of the object requirements to produce the output; The output to the output terminals as the output variable, drive actuators. All the parts of the PLC coordinated control system for the field devices. ( 1) Central processing unit (CPU) is the main purpose of CPUCPU explain and execute the user and the system program, by running the user and the system can complete all given by the control, processing, communication and other functions, control the whole system coordinated work. Commonly used CPU mainly include general microprocessor, microcontroller and bipolar slice machine. ( 2) Random access memory RAM memory modules are used to store the PLC internal input, output, information, and store the internal relay ( Soft relay) , shift register, data registers, timer/counter and the working state of the accumulator, etc, can also be stored user is debugging and modify the program as well as a variety of temporary data, such as intermediate variable. Read-only memory ROM program is used to store system. Can erase the programmable read-only memory EPROM is mainly used to store the operation of the PLC system and monitor, if the user program has been completely debugged, program will also be solidified in the EPROM. ( 3) Input/output module programmable controller is a kind of industrial control computer system, its control object is industrial production process, similar to DCS, it is in connection with the process of industrial production is through the input/output interface module ( I/O) The implementation. I/O module is programmable controller associated with the production process of Bridges. PLC controller connection of process variables on signal classification can be divided into the switch quantity ( The digital quantity) , analog and pulse rate, etc. , the corresponding input/output module can be divided into the switch input module, switch output module, analog input module, analog output module and pulse input module, etc. ( 4) PLC programming device programmer is an important external devices. Programmer will function by programming language users want to PLC controller in the user program memory. Programmer can not only to write, read, modify the program, can also to monitor the working state of the PLC, and the man-machine dialogue interface between the user and the PLC. As to enhance the function of PLC and programming language diversity, programming can be done on the computer.
