SRAM memory card, capacity: 1M bytes.
Size: 45*42.8*3.3mm
Weight: 15g.
Support SD memory card.
High speed universal QCPU support SD memory card,
In order to be able to have a memory card port between SD and PC to easily realize data exchange.
In addition, the SD memory card and the extended SRAM card can be used simultaneously Q172DCPU datasheet PDF catalog Q172DCPU PDF datasheet.
Therefore, the extension of the file register using the extended SRAM card,
SD memory card can be used at the same time to carry out the data file record, a large number of annotation data storage, through the memory card to guide operation Q172DCPU
Better user experience data recording function.
Easy to record, no need to program.
Simply through the special configuration tool wizard to easily complete the settings,
The collected data can be saved in CSV format to SD storage card Q172DCPU datasheet PDF catalog Q172DCPU PDF datasheet.
Can be effectively used to save the CSV file to facilitate the creation of a variety of reference materials,
Including daily reports, generate reports and general reports.
These data can be applied to the data analysis, tracing, etc..
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 Q172DCPU datasheet PDF catalog Q172DCPU PDF datasheet.
Therefore, in the event of failure, can quickly determine the cause, the precise action analysis.Input and output points: 2048 points.
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.
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.
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 applicatiion can store the number of indicators Q172DCPU datasheet PDF catalog Q172DCPU PDF datasheet.
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 Q172DCPU datasheet PDF catalog Q172DCPU PDF datasheet. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
