"2CH RS-232.
QJ71C24N (-R2) through the RS-232 serial communication,
Programming and monitoring of programmable controllers using programming tools.
QJ71C24N (-R2) with the function of the modem corresponding to the public telephone line,
Can be used to initialize the modem, and the connection of the object device processing,
Communication with a remote device, a programming tool, a modem, and a public telephone line Q00JCPU-S8-SET PDF Q00JCPU-S8-SET
Using remote password,
Can be prevented by QJ71C24N (-R2) function of the modem Q series programmable controller for illegal access.
Serial communication module capable of collecting and changing data of programmable controller, monitoring and managing, measuring data collection and so on Q00JCPU-S8-SET PDF.
Can achieve the highest speed of 230.4kbps, the maximum of 960 words (MC protocol communications) of the high speed and large capacity communications.
Can use MC protocol, through the external devices (PC, monitors, etc Q00JCPU-S8-SET PDF. ) to implement the data read / write programmable controller.
By selecting a non sequential protocol and use sequential program for communication control, the programmable controller and the external device (barcode reader and measurement equipment),
Communication with local protocols using external devices MITSUBISHI Programming Manual . "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 majoriity of MITSUBISHI Programming Manual Q00JCPU-S8-SET Manual.
The photoelectric coupler is composed of two luminous two extreme tubes and a photoelectric transistor MITSUBISHI Programming Manual .
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 measurre of how much the user application can store the number of indicators Q00JCPU-S8-SET 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 Q00JCPU-S8-SET Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
