Interface: RS232C.
Transmission distance: 15 meters.
A1SJ71UC24-R2/R4/PR computer communication components can be relied on external intelligent devices such as computers and PLC for communication, the components are as follows:
Full / half duplex transmission,
4 special communication protocols,
No protocol and bidirectional mode,
Protocol selection switch function,
The optional baud rate, the highest 19 A7BDE-J71LP21 PDF A7BDE-J71LP21 2K,
Since the echo diagnostic test. MELSECNET/10, MELSECNET/H coaxial.
Input voltage: DC24V.
How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc A7BDE-J71LP21 PDF. .
MITSUBISHI PLC distribution I/O points and design MITSUBISHI PLC peripheral hardware circuit
Draw the I/O point of the PLC and the input / output device connection diagram or the corresponding table,
This part also can be carried out in second steps.
Design PLC peripheral hardware circuit A7BDE-J71LP21 PDF.
Draw the electrical wiring diagram of the other parts of the system,
Including the main circuit and the control circuit does not enter the PLC, etc..
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram MITSUBISHI User's Manual.
So far the system''s hardware electrical circuit has been determined. 34 point with the wiring transformation adapter 2 line type 16 point input CC-Link unit installation special connection conversion adapterMulti axis positioning controller.
Optical data communication line MITSUBISHI User's Manual.
Program capacity: Max 60K step.
Input / output points: 1920 points.
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 executionn time is accounted for the vast majority of MITSUBISHI User's Manual A7BDE-J71LP21 Manual.
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 measuure of how much the user application can store the number of indicators A7BDE-J71LP21 User's 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 A7BDE-J71LP21 Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
