Using a modem middle modular connector unit faces to transmit data transmission speed: 0.3-14.4kbps.
PLC is the use of " sequential scanning, and constantly circulating " way to work.
That is, in the operation of CPU, PLC according to the user according to the control requirements of the coexistence of the user in the memory of the program,
According to the instruction sequence number (or address number) for periodic cyclic scan, such as no jump instruction,
From the first instruction to the user program execution sequence one by one, until the end of the program,
And then return to the first command, start the next round of the new scan, in the process of each scan,
Also complete the sampling of the input signal and the output status of the refresh and other work.

Also complete the sampling of the input signal and the output status of the refresh and other work.
The most appropriate temperature regulation control (PID control) is possible,
In order to control the PID does not need to specify a special command.
In addition, according to the automatic regulation function,
The automatic setting of PID number is possible.
The length of time required to execute the instruction, the length of the user''s program, the type of instruction, and the speed of the CPU execution are very significant,
Generally, a scanning process, the fault diagnosis time,
Communication time, input sampling and output refresh time is less,
The execution time is accounted for the vast majority of MITSUBISHI A1SJ71CMO-S3
A1SJ71CMO-S3
The response time of PLC is the interval between the time of the change of the external output signal of the PLC and the time of the change of the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the use of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on MITSUBISHI A1SJ71CMO-S3.
This phenomenon is called the I/O delay time effect MITSUBISHI A1SJ71CMO-S3. Type of input: DC source.
Input points: 32 points.
Input voltage: 5/12.
Input current: 1.2/3.3mA.
Connection mode: terminal row.
Common common point: 32.
Functional block diagram language is a kind of PLC programming language, which is similar to digital logic circuit MITSUBISHI Modem module.
The function module is used to represent the function of the module,
Different function modules have different functions MITSUBISHI Modem module.
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 MITSUBISHI Modem module. Input: AC100 ~ 120v/200 ~ 240v,
Output: 5A DC5V.
PLC programming has a wide range of applications, powerful, easy to use, has become one of the main devices of modern industrial automation,
In all areas of industrial production has been widely used,
Applications in other areas (such as civil and home automation) have also been rapidly developed.
It uses programmable memory,
An instruction used to perform logical operations, sequence control, timing, counting and arithmetic operations in its internal storage,
And through digital, analog input and output,
Control of various types of machinery or production processes. Programmable controller and related equipment,
Should be eaasy to make the industrial control system to form a whole, easy to expand the principle design of its functions A1SJ71CMO-S3.
As can be seen from the above definition, PLC is a program to change the control function of the industrial conttrol computer,
In addition to the completion of a wide variety of control functions, as well as with other computer communications networking features MITSUBISHI A1SJ71CMO-S3.
