Input and output points: 512 points.
Input / output data points: 512 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.20.
Coaxial data communication line function.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
Input points 512,
CPU power supply,
Item memory capacity Max 8k,
DC24V power supply.
The popularization and application of PLC programming has been developed rapidly in our country,
It has been widely used in all kinds of mechanical equipment and production process of electrical control devices,
All walks of life have emerged a large number of application of PLC transformation of the results of the equipment MITSUBISHI A2ACPUR21
A2ACPUR21
Understand the working principle of PLC, have the ability to design, debug and maintain the PLC control system,
Has become the basic requirements of modern industry for electrical technicians and engineering students.
Switching value, also known as logic, refers to only two values, 0 or 1, ON or OFF MITSUBISHI A2ACPUR21.
It is the most common control, it is the advantage of PLC control,
Is also the most basic application of PLC.
Structured text language is a programming language that describes a program with a structured description of the text.
It is a programming language similar to a high level language. In large and medium-sized PLC systems, structured text is often used to describe the relationship between the variables in the control system MITSUBISHI A2ACPUR21.
Mainly used for other programming languages more difficult to achieve the user program.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register MITSUBISHI CPU unit.
And then combine the data and the program with CPU.
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive MITSUBISHI CPU unit. Self service (IN, OUT): SI optical cable.
Other aspects (IN, OUT): SI optical cable.
Data link anomaly Bureau bypass.
Inter agency extension.
Cable transformation. Hardware implementation is mainly to control cabinet and other hardware design and field construction MITSUBISHI CPU unit.
Design control cabinet and the operating table and other parts of the electriical wiring diagram and wiring diagram A2ACPUR21.
Electrical interconnection diagram of each part of the design system.
According to the construction drawings of the site wiring, and carry out a detailed inspection.
Because the program deesign and hardware implementation can be carried out at the same time,
So the design cycle of the MITSUBISHI PLC control system can be greatly reduced MITSUBISHI A2ACPUR21.
