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 QD70D4 datasheet PDF catalog QD70D4 PDF datasheet QD70D4
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 QD70D4 datasheet PDF catalog QD70D4 PDF datasheet.
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 QD70D4 datasheet PDF catalog QD70D4 PDF datasheet. 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.
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 logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
SRAM memory card.
RAM capacity: 64KB. Input / output points: 4096 points.
You can use the CF card.
Version OS:VxWorks 5.4.
Simply insert the SD memory card, you can automatically record.
Simply insert the SD in the CPU to save the record setting file, you can automatically start recording.
Even when remote data collection is required,
After receiving a record setting file by mail and copy it to the SD memory card,
Can immediately start recording.
Automatically transfer the record file to the FTP server
Simply by recording the configuration tool to carry out a simple setup,
A data record file stored on the SD memory card can be sent to the FTP server.
Because the recorrd server can handle multiple files, it can reduce the task of management and maintenance QD70D4 datasheet PDF catalog QD70D4 PDF datasheet.
When a failure occurs, it can quickly respond to.
Simply extract the data associated with the problem, do noot have to spend a lot of time to filter a large number of diagnostic data,
So it can quickly determine the cause of the failure, and make the solution QD70D4 datasheet PDF catalog QD70D4 PDF datasheet.
