Input points: 32 points.
Voltage: DC12/24V.
Current: 4/10mA.
Response time: 10ms.
8 points / a common end.
Negative utility.
38 point terminal station.
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 MITSUBISHI A0J2E-E28DT A0J2E-E28DT
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 MITSUBISHI A0J2E-E28DT.
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.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive MITSUBISHI A0J2E-E28DT.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC MITSUBISHI Extension module.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation MITSUBISHI Extension module.
Read only memory. Manufacturers use, content can not be changed, power does not disappear. Input and output points: 480 points
Input / output data points: 480 points
Program capacity: 8K
Basic command processing speed (LD command) s:1 MITSUBISHI Extension module. 25,

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.
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.
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.
Mainly used for other programming languages more difficuult to achieve the user program A0J2E-E28DT.
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.
And then combine the data and the program with CCPU MITSUBISHI A0J2E-E28DT.
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.
