"10BASE5.
Optimal network matching for application purposes and applications,
Seamless communication between different hierarchical systems.
Enhancing the ability of information communication through network.
This is also a major task in the field of automation.
Network environment provided by Q series
Is truly open & seamless Q172CPU Common Instructions.
Including based on universal ethernet,
Achieve easy management of the environment "IE Control CC-Link" controller network,
As well as in its management to achieve a high-speed, high-capacity transmission of the "IE Field CC-Link" field network Q172CPU
Also including Japan''s first, to achieve the world standard,
And get the SEMI certification of the field network "CC-Link",
And inherited the design concept of the provincial distribution network CC-Link/LT" Q172CPU Common Instructions.
And support sensor networks "AnyWire",
To enrich the lineup flexibility to integrate the various layers of automation network.
Ethernet interface module capable of selecting the most suitable system and object device.
Support 100BASE-TX, can speed up the transmission speed. (QJ71E71-100)
Data communication can be performed between programmable controller CPU using special instructions Q172CPU Common Instructions.
Can use the HTTP protocol, through the Web browser on the PC access to the soft element of the programmable controller.
PC (Web) on the use of the communication program library and sample screen can be obtained by download services.
Can connect a number of programming tools to improve the efficiency of debugging.
Make use of e-mail function, through the mail server to send e-mail (ASCII format) and attachments (binary, ASCII and CSV format).
The KeepAlive function can be used to perform the existence of the object equipment inspection, and keep the connection in the open state.
This can be used to ensure connectivity and to quickly find errors. "Input and output points: 4096 points.
Input / output data points: 8192 points.
Program capacity: 124k.
Basic command processing speed (LD command) S:0.075.
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 Q172CPU 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 Q172CPU Programming Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
