Special multi axis positioning controller for NSD servo system.
Optical data communication line.
Program capacity: Max 60K step.
Input / output points: 1920 points AY40-UL PDF.
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 AY40-UL
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 AY40-UL PDF.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
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 AY40-UL PDF.
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 MITSUBISHI User's Manual AY40-UL Manual .
The photoelectric coupler is composed of two luminous two extreme tubes and a photoelectric transistor MITSUBISHI User's Manual.
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 User's Manual. Output type: transistor source.
Output points: 16 points.
Load voltage: DC5/12/24.
Load current: 2A.
Connection mode: terminal row.
Common public end points: 8.
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 combinaation 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 AY40-UL User's Manual.
So, sometimes also known as the order control.
And seqquential control is divided into manual, semi-automatic or automatic AY40-UL Manual .
And the control principle is decentralized, centralized and hybrid control three.
