OFF leakage current: 0.1mA.
Output protection function: No.
Rated load voltage / current: DC12V/DC24V/0.5A.
External connection: 1 wire.
According to the external connection mode and the external equipment input and output specifications,
Choose from a rich product lineup AJ71ATT21B.
Finger protection through the upper part of the terminal,
The human body will not be exposed to live parts,
Therefore, the terminal station type remote I/O module can be directly mounted to the machine tool AJ71AT21B. 10BASE5/10BASE2
Control layer /MELSECNET/10 (H) is the middle layer of the whole network system,
Control network which is convenient and high speed processing data transmission between PLC, CNC and other control equipment AJ71AT21B.
As MELSEC control network MELSECNET/10,
With its good real-time performance, simple network settings, no procedures of the network data sharing concept,
As well as the redundant circuit and so on, has obtained the very high market appraisal,
The number of devices to reach the highest in japan,
In the world is also one of the few MITSUBISHI AJ71AT21B.
And MELSECNET/H not only inherited the excellent characteristics of MELSECNET/10,
Also makes the network real-time better, more data capacity,
Further adapt to the needs of the market.
Twisted pair cable.
Single bus MITSUBISHI AJ71AT21B.
MELSECNET/B (Master / local station).
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 AJ71AT21B.
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc.. A set of 5 (LOGO removable, man-machine interface provides one).
Applicable model: A95_GOT (-M3). RS-232 2 channel.
Transfer speed: 0.3-19.2kbps.
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 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.
Semiconductor circuit with memory function.
System program memory and user memory.
System program memory for storing system proggram,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation AJ71AT21B.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
