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 A171SCPU PDF catalog A171SCPU
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 A171SCPU PDF catalog .
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. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
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 A171SCPU PDF catalog MITSUBISHI A171SCPU PDF datasheet.
The photoelectric coupler is composed of two luminous two extreme tubes and a photoelectric transistor MITSUBISHI A171SCPU PDF datasheet.
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 MITSUBISHI A171SCPU PDF datasheet. Pulse input: DC input.
Default input: DC input.
Count range: 0~16777215.
Number of statioons: 4 stops A171SCPU datasheet.
Station type: remote equipment station.
Configuration of master / local station,
In addition to the other site network with different CC-Link in addition to the main station and the remote station configuration caan also be the main station and the local station configuration A171SCPU PDF catalog .
A local PLC can communicate with the master station PLC and other remote workstations.
