10BASE5.
For Q mode.
Control layer /MELSECNET/10 (H) is the middle layer of the whole network system,
Control network which is convenient and high speed processing data transmission between PLC, CNC and other control equipment AJ35PTF-24S PDF.
As MELSEC control network MELSECNET/10,
With its good real-time performance, simple network settings, no procedures of the network data sharing concept,
As well as the redundant circuit and so on, has obtained the very high market appraisal,
The number of devices to reach the highest in japan,
In the world is also one of the few AJ35PTF-24S
And MELSECNET/H not only inherited the excellent characteristics of MELSECNET/10,
Also makes the network real-time better, more data capacity,
Further adapt to the needs of the market AJ35PTF-24S PDF. I/O points: 1024.
Processing speed: sec/ 0.15u step.
Memory capacity: 256K bytes.
Program capacity: 30K step.
PLC programming is a digital computing operation of the electronic system,
Designed for applications in industrial environments AJ35PTF-24S PDF.
It uses programmable memory,
An instruction used to perform logical operations, sequence control, timing, counting and arithmetic operations in its internal storage,
And through the digital, analog input and output, control of various types of machinery or production process MITSUBISHI User's Manual.
Programmable controller and related equipment,
Should be easy to make the industrial control system to form a whole, easy to expand the principle design of its functions. Input and output points: 2048 points.
Input / output data points: 2048 points MITSUBISHI User's Manual.
Program capacity: 30K.
Basic command processing speed (LD command) s:0.15.
Optical data communication line function (GI cable).
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the powwer supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure MITSUBISHI User's Manual AJ35PTF-24S Manual .
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
User program storage capacity: it is a meassure of how much the user application can store the number of indicators AJ35PTF-24S User's 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 AJ35PTF-24S Manual . Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
