MITSUBISHI AJ71PT32-S3 MELSECNET/MINI-S3 module AJ71PT32-S3


Input voltage range: DC110V.
Output voltage: DC5V.
Output current: 8A.
I/O points is an important indicator of PLC.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest.
The input and output points and types of PLC should be determined according to the analoog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point AJ71PT32-S3 AJ71PT32-S3.
Taking into account the future adjustment and expansion,
In general should be estimated on the total number of points plus the amount of spare 20%~30%.
The following describes the centralized control system I/O points of the estimate. A1SI61 is designed to control the application of mechanical devices that require high speed response time AJ71PT32-S3.
A1SI61 temporarily stop running in order to generate an interrupt signal when the program is running,
And according to the interrupt vector to execute the corresponding interrupt handler.
The interrupt start condition can be selected according to the type of the connected device,
That is, the rising edge of the interrupt signal can be selected as a starting signal, and the falling edge of the interrupt signal can be selected as an interrupt MITSUBISHI AJ71PT32-S3.
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 AJ71PT32-S3.
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 MITSUBISHI AJ71PT32-S3.
The instruction list programming language is a programming language similar to assembly language mnemonic,
As well as assembly language by the operation code and the number of operations.
In the case of the computer for the PLC handheld programmer compile user program.
At the same time, the programming language of the instruction list corresponds to the ladder diagram programming language,
In PLC programming software can be converted to each other. Figure 3 is the instruction sheet corresponding to the ladder diagram of figure 2PLC.
The characteristics of instruction table programming language is used to represent mnemonic operation function,
Easy to remember, easy to grasp;
In the handheld programmer on the keyboard using the mnemonic representation, easy to operate, can be programmed in computer;
There is a one-to-one correspondence between the ladder diagram and the ladder diagram. Its characteristics are basically consistent with the ladder diagram language.
Fiber optic cable / twisted pair cable.
Single bus.
Control unit.
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 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 wwrong operation of the system AJ71PT32-S3.
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..
