GI-62.5/125 optical cable.
Double ring.
PLC to PLC network (control station / common station) / remote I/O net (remote master station).Input and output points: 4096 points.
Input / output data points: 8192 points.
Program capacity: 124k.
Basic command processing speed (LD command) S:0.075.
Multiple CPU (co processor loading) Q04UDHCPU Common Instructions Manual Q04UDHCPU Programming Manual.
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 Q04UDHCPU
The photoelectric coupler is composed of two luminous two extreme tubes and a photoelectric transistor Q04UDHCPU Common Instructions Manual Q04UDHCPU Programming 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 Q04UDHCPU Common Instructions Manual Q04UDHCPU Programming 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.
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 Q04UDHCPU Common Instructions Manual Q04UDHCPU 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 Q04UDHCPU Common Instructions Manual Q04UDHCPU Programming Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
