Input / output points: 4096 points.
Size side mode: small end mode.
SD memory card: available.
6.8.1 OS:VxWorks edition.
Advanced information processing and stable I/O control of high-end type.
C language controller is a long term stable supply, high reliability, high performance, flexible MELSEC on the implementation of the C language program revolutionary open platform Q25PHCPU Common Instructions 1/2 Manual Q25PHCPU Programming Manual
Q25PHCPU
Including pre installed VxWorks,
This C language controller can be used with various modules of the MELSEC-Q series,
Partner products and open source,
Client program assets, such as portfolio use to build a variety of systems.
As can be used in all scenarios, can replace the computer, a new computer platform,
C MELSEC language controller stronger, simpler, higher performance, more flexible, in the future will also continue to continue to develop Q25PHCPU Common Instructions 1/2 Manual Q25PHCPU Programming Manual . SRAM+E2PROM memory card.
RAM capacity: 256KB.
E2PROM capacity: 256KB. Program capacity: 8K step.
Input / output points: 1024 points.
Number of input and output elements: 2048.
Continue to go beyond, to climb the peak of Q series.
Strengthen security function.
Can be set up to 32 characters of the file password Q25PHCPU Common Instructions 1/2 Manual Q25PHCPU Programming Manual .
In addition to the English letters, numbers, but also the use of special characters,
To further enhance the security of the password.
In addition, only pre registered devices are allowed to access CPU,
To intercept unauthorized access to unauthorized users.
Therefore, it is important to prevent the outflow of important program assets and protect intellectual property rights.
CPU module expansion standard RAM (max 8MB).
Can be used with the SD memory card at the same time.
Continuous access file register.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 application can store thhe number of indicators Q25PHCPU Common Instructions 1/2 Manual Q25PHCPU 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 Q25PHCPU Common Instructions 1/2 Manual Q25PHCPU Programming Manual . Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
