SRAM memory card.
RAM capacity: 1MB. 5 slots.
Extended substrate.
No need to install power module.
Used to install Q series modules.
Reduce system downtime recovery time.
With a simple operation, you can back up all the data in the CPU to the memory card.
Through regular backup, can be the latest parameters, procedures, etc Q173HCPU datasheet PDF catalog Q173HCPU PDF datasheet. to save the storage card Q173HCPU
In the event of a CPU failure, after the replacement of CPU, can be a simple operation,
Restore the system by using the data storage card in advance.
Therefore, it is not necessary to spend time to manage the backup data, but also can shorten the recovery time of the system shutdown.
Wider application range, more advanced.
Leading in the era of the Q series CPU products Q173HCPU datasheet PDF catalog Q173HCPU PDF datasheet.
Q series CPU products a wide range of applications,
Provide programmable controller, process, redundancy, C language, movement, manipulator, CNC all kinds of CPU,
In order to meet the needs of various control.
Through the multi CPU configuration, can be based on the use of the scale, purpose,
Construction of the best system to meet the requirements of all kinds of control Q173HCPU datasheet PDF catalog Q173HCPU PDF datasheet.
In addition, the high reliability system can be constructed by the redundant system,
Even if a fault occurs, the system can continue to run.Input and output points: 1024 points.
Input / output data points: 8192 points.
Program capacity: 60k.
Basic command processing speed (LD command) S:0.2.
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 Q173HCPU datasheet PDF catalog Q173HCPU 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 Q173HCPU datasheet PDF catalog Q173HCPU PDF datasheet. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
