I/O slots: 2 slots.
Can you install the power module.
Outline dimension: 155*130.
There are two types of extended floor,
A power module can be inserted, and the other one is not.
The choice of any type of substrate depends on the total DC5V current consumption and the power supply on the CPU main substrate AJ71C21 datasheet PDF catalog AJ71C21 PDF datasheet.
If the total demand is less than the power output, no additional power supply,
Then you can choose a more economical expansion board AJ71C21
Both ends of the main base plate of the CPU have an expansion interface, and can be used for extending the cable connection. Analog channel: 12 channels.
Input / output (resolution): 0 ~ 4000.
Conversion speed: 100ms/12 channel.

Power supply: AC170V ~ 264V.
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program.
Procedures to meet the requirements of system control as the main line,
Write one by one to achieve the control function or the sub task of the program,
Gradually improve the functions specified by the system.
MITSUBISHI PLC detection, fault diagnosis and display and other procedures AJ71C21 datasheet PDF catalog AJ71C21 PDF datasheet.
These procedures are relatively independent, generally in the basic completion of the program design and then add.
Hardware simulation method is to use a number of hardware equipment to simulate the generation of the signal,
The signals are connected to the input end of the PLC system in a hard wired way, and the timeliness is strong.
Software simulation method is in the MITSUBISHI PLC in the preparation of a set of simulation program,
The simulation provides the field signal, which is simple and easy to operate, but it is not easy to guarantee the timeliness.
Simulation of the process of debugging, debugging method can be used to segment, and the monitoring function of programmer. Coaxial data link anomaly station.

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 difficult to achieve the user prograam AJ71C21 datasheet PDF catalog AJ71C21 PDF datasheet.
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 AJ71C21 datasheet PDF catalog AJ71C21 PDF datasheet.
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.
