MITSUBISHI Q20UDHCPU Multiple CPU System Manual Q20UDHCPU User's Manual
Product model: Q20UDHCPU
Name: CPU
Brand: MITSUBISHI
Sort: Multiple CPU System User's Manual
File language: English
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.
Therefore, in the event of failure, can quickly determine the cause, the precise action analysis Q20UDHCPU Multiple CPU System Manual Q20UDHCPU User's Manual. Input and output points: 2048 points Q20UDHCPU
Input / output data points: 8192 points.
Program capacity: 92k.
Basic command processing speed (LD command) S:0.15.
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 Q20UDHCPU Multiple CPU System Manual Q20UDHCPU User's Manual.
The photoelectric coupler is composed of two luminous two extreme tubes and a photoelectric transistor.
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 Q20UDHCPU Multiple CPU System Manual Q20UDHCPU User's 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. 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 a measure of how much the user application can store the number of indicators Q20UDHCPU Multiple CPU System Manual Q20UDHCPU 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 Q20UDHCPU Multiple CPU System Manual Q20UDHCPU User's Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
