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 MITSUBISHI PLC Programming Manual Q12PHCPU
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 MITSUBISHI PLC Programming 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 MITSUBISHI PLC Programming 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 Q12PHCPU Programming Manual.
The output signal has a linear relationship with the input signal in the linear operating region of the photoelectric coupler Q12PHCPU Programming Manual.
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 Q12PHCPU Programming Manual.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4. Input: 4 channels.
Thermocouple (C1602~1995 JIS).
Micro voltage (-100mV~100mV).
Conversion speed: (sampling period x3) /1 channel.
18 point terminal station.
Most suitable for process control of isolated analog modules.
Temperature data can be collected by connecting thermocouple / thermal resistance.
Products can choose multi-channel (8 channel) input type and channel isolation type.
Customers can choose the most suitable model according to the intended use.
Auto backup key data
Save the program and parameter files automatically to the program memory (ROM Flash) without using the backup battery,
To prevent the loss of the program and the parameters due to forgetting to replace the battery.
In addition, the soft component data and other important data can be backed up to the standard ROM,
In order to avoid during the long holiday and other planned downtime,
The data is lost due to battery depletion.
The next time the power is turned on, the backup data will be automatically restored.
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 bbackup, can be the latest parameters, procedures, etc Q12PHCPU Manual. to save the storage card.
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 ccard in advance MITSUBISHI PLC Programming Manual.
Therefore, it is not necessary to spend time to manage the backup data, but also can shorten the recovery time of the system shutdown.
