MITSUBISHI A3UCPU Dedicated Instructions Manual A3UCPU Programming Manual
Product model: A3UCPU
Name: PLC
Brand: MITSUBISHI
Sort: Dedicated Instructions Programming Manual
File language: English
Input voltage range: AC100-120V/AC200-240V.
Output voltage: DC24V.
Output current: 1.2A additional power supply unit.
I/O points is an important indicator of PLC.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest A3UCPU Dedicated Instructions Manual A3UCPU Programming Manual.
The input and output points and types of PLC should be determined according to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point A3UCPU
Taking into account the future adjustment and expansion,
In general should be estimated on the total number of points plus the amount of spare 20%~30%.
The following describes the centralized control system I/O points of the estimate A3UCPU Dedicated Instructions Manual A3UCPU Programming Manual. 26 point line conversion adapter 1 line type 16 input CC-Link unit installation special connection conversion adapterCPU connection program input device.
ACPU use. Multi axis positioning controller.
Program capacity: Max 60K step.
Input / output points: 1920 points.
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 A3UCPU Dedicated Instructions Manual A3UCPU Programming Manual.
The photoelectric coupler is composed of two luminous two extreme tubes and a photoelectric transistor.
Light emitting 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.
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.
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.
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 stoore the number of indicators A3UCPU Dedicated Instructions Manual A3UCPU Programming 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 llogical operation instructions each account for 1 words A3UCPU Dedicated Instructions Manual A3UCPU Programming Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
