RS-232:1 channel, RS-422:1 channel.
BASIC program mode (A3MCPU corresponding): BASIC console interface to use.
Sequential program mode (program controller CPU correspondence): non sequential computer connection interface and use.
How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc A1SD51S Command. .
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 A1SD51S
Design PLC peripheral hardware circuit.
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 A1SD51S Command. .
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram.
So far the system''s hardware electrical circuit has been determined. Screw, 2 piece type terminal.
Current output module.
Number of channels: 4 channels.
Number of stations: 2 stops A1SD51S Command.
Station type: remote equipment station.
High speed data transfer of up to 10Mbps;
The development of CC-LINK is not only to meet the control of high speed remote I/O,
But also to meet the high speed of the field of information control.
In order to achieve this goal, the transmission speed of CC-LINK is compared with that of the previous live network system to add 40 to 10Mbps.
Such a high speed can not affect the speed of the machine control while allowing a large number of data communication. Multi axis positioning controller.
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 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 the number of indicators A1SD51S 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 A1SD51S Programming Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
