MITSUBISHI Q12HCPU Programming Manual PLC Special Instructions Manual

Program capacity: 28K step.
Input / output points: 1096 points.
Number of input and output elements: 8192.
Processing speed: 0.034 subtle.
Support RS232.
CPU module expansion standard RAM (max 8MB).
Can be used with the SD memory card at the same time.
Continuous access file register.
Ultra high speed processing, production time is shortened, better performance Q12HCPU Manual.
As applications become larger and more complex, it is necessary to shorten the system operation cycle time Q12HCPU
The operation period can be shortened by the super high basic operation speed 1.9ns.
In addition to achieve in the past with the control of single-chip high-speed control,
The system performance can be improved by reducing the total scan time,
To prevent any possible performance bias Q12HCPU Manual. Input and output points: 4096 points.
Input / output data points: 8192 points.
Program capacity: 124k.
Basic command processing speed (LD command) S:0.075.
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 Q12HCPU Manual.
The photoelectric coupler is composed of two luminous two extreme tubes and a photoelectric transistor MITSUBISHI PLC 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 MITSUBISHI PLC Manual.
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.
When the switch is off, the diode does not emit light, and the transistor is not on the way MITSUBISHI PLC Manual. Internal circuit input signal.
It is through the input interface circuit to the external switch signal into PLC internal can accept the digital signal.
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 aa measure of how much the user application can store the number of indicators Q12HCPU 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.
General llogical operation instructions each account for 1 words Q12HCPU Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
