Input and output points: 1024 points.
Input / output data points: 8192 points.
Program capacity: 60k.
Basic command processing speed (LD command) S:0.2.
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 Q172DSCPU User's Manual Q172DSCPU
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 Q172DSCPU User's Manual.
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 Q172DSCPU User's Manual. 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.
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 logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4. Module connector 1Ch.
1ch RS-232.
The possibility of expanding control with intelligent function.
Providing a variety of analog modules, is the ideal choice for process control applications.
Can also meet the needs of high speed, high precision control.
Most suitable analog modules for high speed conversion control.
Can provide a variety of analog and digital analog conversion module products.
These modules have a variety of functions, in the connection of equipment, to achieve the greatest flexibility.
Can meet the inverter control, such as high-speed conversion needs.
Easy connection programming tool via ethernet.
Programming tools (Workks2 GX, Developer GX) and CPU direct connection (1 to 1),
No need to carry out the IP address settings Q172DSCPU Manual. And there is no need to select the cable, the straight line and the cross line can be used.
Therefore, this connection method annd the use of USB, can easily communicate with the CPU,
Even the operators are not familiar with the network settings can easily establish a connection Q172DSCPU Manual.
