MITSUBISHI Q02CPU Programming Manual (PID Control Instructions) PDF

SRAM+E2PROM memory card.
RAM capacity: 32KB.
E2PROM capacity: 32KB. Input and output points: 512 points.
Input / output data points: 8192 points.
Program capacity: 28k Q02CPU PDF.
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 Q02CPU
The photoelectric coupler is composed of two lumiinous two extreme tubes and a photoelectric transistor Q02CPU PDF Q02CPU 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 Q02CPU 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 MITSUBISHI Programming 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 Programming Manual .
User program storage capacity: it is a measure of how much the user aapplication can store the number of indicators Q02CPU 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 MITSUBISHI Programming Manual .
General llogical operation instructions each account for 1 words Q02CPU Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
