Programmable Logic Controller A2ASCPU Common Instructions Manual MITSUBISHI A2ASCPU Programming Manual
Product model: A2ASCPU
Name: Programmable Logic Controller
Brand: MITSUBISHI
Sort: Common Instructions Programming Manual
File language: English
Module for A3VTS multiplex system.
MITSUBISHI PLC detection, fault diagnosis and display and other procedures.
These procedures are relatively independent, generally in the basic completion of the program design and then add.
MITSUBISHI PLC protection and chain procedures.
Protection and chain is an indispensable part of the program, must be carefully considered A2ASCPU Manual.
It can avoid the control logic confusion caused by illegal operations A2ASCPU Multi axis positioning controller.
Optical data communication line.
Program capacity: Max 60K step.
Input / output points: 1920 points.
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 A2ASCPU Manual.
Photoelectric three levels: in the light of the light signal conduction, the degree of light signal and the intensity of the light signal.
The output signal has a linear relationship with the input signal in the linear operating region of the photoelectric coupler.
User program storage capacity: it is a measure of how much the user application can store the number of indicators A2ASCPU Manual.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General logical operation instructions each account for 1 words MITSUBISHI A2ASCPU Programming Manual . Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4 MITSUBISHI A2ASCPU Programming Manual .
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 A2ASCPU Programming Manual .
The photoelectric coupler is composed of two luminous two extreme tubes and a photoelectric transistor.
Light emiitting diode two: the input of a photo coupler and the change of electrical signal,
The light signal is generated by the light emitting diode, which is the same as the input signal A2ASCPU Common Instructions.
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 A2ASCPU Manual.
