SI/QSI/H-PCF/ broadband H-PCF optical cable.
Double circuit.
Controller network (control station / common station) / remote I/O network (remote master station).
With external power supply function.
MELSECNET/H network module capable of composing large scale flexible network system.
The MELSECNET/H network system includes the PLC network of the control station and the communication between the stations and the remote I/O network in the remote station remote I/O station Q68DAV PDF datasheet Q68DAV
Optical fiber loop system...... High speed communication of 10Mbps/25Mbps is realized.
The distance between stations, the length of the total cable length, strong anti-interference.
Coaxial bus system...... Using low cost coaxial cable, the network construction cost is lower than that of the optical fiber loop network Q68DAV PDF datasheet .
Twisted pair bus system...... Combined with high performance price ratio network module and twisted pair cable,
The construction cost of network system is very low.Master station.
Province distribution network module in cabinet and device.
Link to connect the 64 stations when the fastest scanning time for 1 Q68DAV PDF datasheet . 2ms (rate 2.5Mbps).
According to the transmission distance, the transmission rate is selected from 2.5Mbps, 625kbps and 156kbps.
CC-Link/LT from the station does not need any parameter settings.
Only need to set up the transmission speed in the master module, you can use the remote I/O MITSUBISHI Q68DAV PDF catalog.
QJ61CL12 can be used as the main station of CC-Link/LT.Input and output points: 4096 points MITSUBISHI Q68DAV PDF catalog.
Input / output data points: 8192 points.
Program capacity: 124k.
Basic command processing speed (LD command) S:0.075.
Multiple CPU (co processor loading).
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 Q68DAV PDF catalog.
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 measurre of how much the user application can store the number of indicators Q68DAV datasheet.
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 Q68DAV PDF datasheet . Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
