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 Q172DCPU User's Manual Q172DCPU
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 Q172DCPU 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 Q172DCPU User's 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 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. Output points: 16 points.
Output voltage and current: DC12~24V; 0.5A/ point; 4A/ common.
OFF leakage current: 0.1mA.
Response time: 1ms.
16 points and 1 common ends.

Ultra high speed processing, production time is shortened, better performance.
As applications become larger and more complex, it is necessary to shorten the system operation cycle time.
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.
Convenient processing of large capacity data.
In the past can not achieve the standard RAM and SRAM card file register area of continuous access,
The boundary of each area should be considered in programming.
The SRAM 8MB extension card is installed in the high speed universal QCPU,
Standard RAM can be used as a continuous file register,
Capacity up to 4736K words, thus simplifying the programming.
Thus, even if the memory space of the soft element is insufficient,
Can also be installed by the expansion of SRAM card, easy to extend the file register area.
The address register is extended to 32 bits, which can be programmed to go beyond the traditional 32K word,
And to achieve the extension to the file register to all regions of the file register.
In addition, the processing speed of the index modification plays an important role in the efficient operation of structured data (array),
The speed has been improved.
When the index is used to modify the program repeatedly (e.g. from FOR to NEXT), the scan time can be reduced.
With the help of sample tracking function, the starting time is shortened
By using the sampling and tracking function, it is convenient to analyze the data when the fault occurs,
Testing procedures for the time, etc., can shorten the time of failure analysis and start-up time.
In addition, the multi CPU system also helps to determine the ddata transceiver time between the CPU module Q172DCPU Manual.
Can be used to analyze the data collected by programming tools,
In the form of charts and trend charts, the data changes of the bit soft element and the word soft element can be easily diisplayed Q172DCPU Manual.
And the sampling tracking results can be stored in LogViewer GX form CSV,
By recording data display and analysis tool LogViewer GX to display.
