A70LX-S3 A scan cycle is divided into the input sample, the program execution, the output refresh MITSUBISHI A70LX-S3

Brand: MITSUBISHI
Name: Input module
Model: A70LX-S3
Input unit (upper / lower limit LS signal) (NSD servo system)
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC.
System program memory for storing system program,
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.

CPU connection program input device.
ACPU use. 2 axes.
2 axis linear interpolation.
Control unit: pulse, mm, inch, degree.
Determine the location of the number of data: 400/1 axis.
40 pin connector.
Control mode: position automatic acceleration and deceleration time: 64-4999ms pulse train output.
The working process of the input interface circuit: when the switch is closed, the diode light,
The transistor is then guided to the internal circuit and input signal under the irradiation of the light MITSUBISHI A70LX-S3 A70LX-S3
When the switch is off, the diode does not emit light, and the transistor is not on the way. Internal circuit input signal.
It is through the input interface circuit to the external switch signal into PLC internal can accept the digital signal MITSUBISHI A70LX-S3.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC MITSUBISHI A70LX-S3.
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 MITSUBISHI Input module.
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 MITSUBISHI Input module.
MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian.
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process MITSUBISHI Input module. Ethernet network module 10BASE-T/10BASE5
Equipment layer / field bus CC-Link device layer is the PLC and other control devices and sensors and drive devices connected to the field network,
Network for the lowest layer of the whole network system.
Using CC-Link field bus connection, the number of wiring is greatly reduced,
Improve the maintainability of the system.
And, not just the amount of data ON/OFF and other switches,
Can also be connected to the ID system, bar code reader, invertter, man-machine interface and other intelligent devices,
From the completion of a variety of data communication, the management of the terminal production information can be realized,
On the centralized management of the state oof the machine movement,
Make maintenance work efficiency also greatly improved MITSUBISHI A70LX-S3 A70LX-S3.
Q series PLC in the use of CC-Link function better,
And easier to use.
