SI/QSI/H-PCF/ broadband H-PCF optical cable.
Double circuit.
Controller network (control station / common station) / remote I/O network (remote master station).
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 Q20UDEHCPU Common Instructions Manual Q20UDEHCPU Strctured Programming Manual Q20UDEHCPU
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 Q20UDEHCPU Common Instructions Manual Q20UDEHCPU Strctured Programming Manual.
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.GI-62.5/125 optical cable.
Double ring.
Remote I/O net (remote I/O station).Control axis: maximum 32 axes.
Teaching operation function: No.
To stop the speed control function at the specified location Q20UDEHCPU Common Instructions Manual Q20UDEHCPU Strctured Programming Manual.
The servo motor can rotate at a predetermined speed,
After starting the specified location to stop the instruction,
Can be set in advance to stop the location.
You can change the speed by changing the value of the options at the time of the operation,
You can also change the acceleration / deceleration time.
Phase compensation function.
The mixed function of virtual mode and real mode.
Smooth clutch linear acceleration / deceleration function.Input and output points: 4096 points.
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.
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 Q20UDEHCPU Common Instructions Manual Q20UDEHCPU Strctured 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 Q20UDEHCPU Common Instructions Manual Q20UDEHCPU Strctured Programming Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
