MITSUBISHI QJ71E71-B2  User's Manual (Hardware) PDF

Extended SRAM card 8MB
To record the change of control data without missing.
Data can be collected in a time interval or in a millisecond time interval,
To record the change of the specified control data without any omission QJ71E71-B2  PDF.
Therefore, in the event of failure, can quickly determine the cause, the precise action analysis.Input and output points: 1024 points.
Input / output data points: 8192 points QJ71E71-B2 
Program capacity: 60k.
Basic command processing speed (LD command) S:0.2.
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 QJ71E71-B2  PDF.
The photoelectric coupler is composed of two luminous two extreme tubes and a photoelectric transistor QJ71E71-B2  PDF QJ71E71-B2  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.
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 User's 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 User's Manual.
User program storage capacity: it is a measure of how much the user application can store the number of indicators QJ71E71-B2  User's 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 QJ71E71-B2  Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
