10BASE-T.
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.
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 A3HCPUP21 Common Instructions Manual A3HCPUP21 Programming Manual
A3HCPUP21
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 A3HCPUP21 Common Instructions Manual A3HCPUP21 Programming Manual . Output type: transistor output, drain type.
Output points: 32 points.
OFF leakage current: 0.1mA.
Output protection function: No.
Rated load voltage / current: DC12V/DC24V/0.5A.
External connection: 1 wire.
According to the external connection mode and the external equipment input and output specifications,
Choose from a rich product lineup.
Finger protection through the upper part of the terminal,
The human body will not be exposed to live parts,
Therefore, the terminal station type remote I/O module can be directly mounted to the machine tool A3HCPUP21 Common Instructions Manual A3HCPUP21 Programming Manual . Cable length 1m; used in A6TE2-16SRN.Input and output points: 512 points.
Input / output data points: 512 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.20.
Coaxial data communication line function.
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 measure of how much the user application can store the number of indicators A3HCPUP21 Common Instructions Manual A3HCPUP21 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 A3HCPUP21 Common Instructions Manual A3HCPUP21 Programming Manual . Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
