3C-2V/5C-2V coaxial cable between the single bus PC network (control station / common station) / remote I/O network (remote master).
Q mode.
Then CPU according to the function of the system (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program.
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.
And then output to the output interface, control the external drive.
Semiconductor circuit with memory function.
System program memory and user memory.
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
User memory: user program storage area and work data storage area.
Composed of random access memory (RAM). User use.
Power cut off. Commonly used efficient lithium battery as a backup power supply, life is generally 3~5 years.
Axis of control: 1.
A1SD75 series components show the MITSUBISHI in the manufacture and design of CNC, frequency converter,
Integrated technical experience in servo system and PLC.
These components have a wealth of features that are sufficient to meet the highest requirements in the application of positioning control MITSUBISHI A1SJ71QBR11.
Up to 3 axis linkage operation,
In low cost motion control applications, this component can be used to control the operation of a multi - to 3 axis, which can be used to account for only one slot
A1SJ71QBR11 Type of input: DC leakage.
Input points: 32 points.
Input voltage: DC24.
Input current: 7mA.
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 A1SJ71QBR11.
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 MITSUBISHI A1SJ71QBR11. SRAM+E2PROM memory card.
RAM capacity: 128KB.
E2PROM capacity: 128KB. Enter 32 points.

40 pin connector.
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.
Switch volume control is designed to,
According to the current input commbination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order A1SJ71QBR11.
So, sometimes also known as the order control.
And seqquential control is divided into manual, semi-automatic or automatic A1SJ71QBR11.
And the control principle is decentralized, centralized and hybrid control three.
