A9GT-J71E71-T PDF datasheet MITSUBISHI A9GT-J71E71-T datasheet PDF catalog

Input and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:1.0.
Coaxial data communication line function.
User program storage capacity: it is a measure of how much the user application can store the number of indicators MITSUBISHI A9GT-J71E71-T PDF catalog.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words A9GT-J71E71-T 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.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure MITSUBISHI A9GT-J71E71-T PDF catalog.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance. Number of channels: 2 channels.
Input signal: RS422A EIA.
Counter: 10KPPS/1 with the highest frequency.
A1SD62, A1SD62D and A1SD62E are 2 channel high speed counter components for AnS series PLC MITSUBISHI A9GT-J71E71-T PDF catalog.
They are improved in comparison with A1SD61 in the following ways: the density of channels.
In order to require a higher resolution and operating speed of the application to provide a higher count rate, reduce costs.
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.
Functional block diagram language is a kind of PLC programming language, which is similar to digital logic circuit.
The function module is used to represent the function of the module,
Different function modules have different functions.
Functional module figure programming language features: functional block diagram programming language is characterized by a functional module for the unit,
Analysis and understanding of the control scheme is simple and easy: function module is to use graphical form of expression,
Intuitive, for a digital logic circuit based on the design of the staff is very easy to master the programming;
Control system with complex scale and complex control logic,
Because the function module diagram can clearly express the function relation, the programming debugging time is greatly reduced.
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.
PLC user program is designed according to the control system of the process control requirements,
PLC programming language through the preparation of specifications, in accordance with the actual needs of the use of the function to design A9GT-J71E71-T PDF datasheet.
As long as the user caan master some kind of standard programming language,
To be able to use PLC in the control system,
To achieve a variety of automatic control functions A9GT-J71E71-T PDF datasheet.
