MITSUBISHI A2NCPUP21-S3 Product information and technical parameters:
Brand: MITSUBISHI
Name: CPU unit
Model: A2NCPUP21-S3
Input and output points: 512 points.
Input / output data points: 512 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:1.0.
Optical data communication line function (GI cable).
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.
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.

SRAM capacity: 32K bytes.
AD59 (-S1) data storage.
On-line debugging is the process that will through the simulation debugging to further carry on the on-line unification to adjust.
On-line debugging process should be step by step,
From MITSUBISHI PLC only connected to the input device, and then connect the output device, and then connect to the actual load and so on and so on step by step MITSUBISHI A2NCPUP21-S3 A2NCPUP21-S3
If you do not meet the requirements, the hardware and procedures for adjustment.
Usually only need to modify the part of the program can beEthernet network module 10BASE-T/10BASE5.
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 MITSUBISHI A2NCPUP21-S3.
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 MITSUBISHI A2NCPUP21-S3.
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. Input and output points: 512 points.
Input / output data points: 512 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:1.0.
Optical data communication line.
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 instructionss for 2~4 A2NCPUP21-S3.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure A2NCPUP21-S3.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
