MITSUBISHI QJ71LP21-25 reference Manual (PLC to PLC network) PDF

Input and output points: 512 points.
Input / output data points: 8192 points.
Program capacity: 28k.
Basic command processing speed (LD command) S:0.2 QJ71LP21-25 PDF.
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 QJ71LP21-25
The photoelectric coupler is composed of two luminous two extreme tubes and a photoelectric transistor QJ71LP21-25 PDF.
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 QJ71LP21-25 PDF QJ71LP21-25 Manual.
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 reference 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 MITSUBISHI reference Manual.
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.
General logical operation instructions each account for 1 words MITSUBISHI reference Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
Control axis: up to 32 axes.
Servo amplifier connection mode: SSCNET III /H (2 system).
Can be carried out with a high degree of control, free correspondence QJ71LP21-25 reference Manual.
Large scale and medium scale system.
Maximum number of control axis: 32 axis (Q173DSCPU), 16 axis (Q172DSCPU).
Programmable controller CPU and C language controller can be selected according to the purpose QJ71LP21-25 Manual.
By using 3 sets of Q173DSCPU, 96 axes can be controlled.
Support security monitoring function, visual system.
