MITSUBISHI A3NCPUP21-S3 datasheet PDF catalog A3NCPUP21-S3 PDF datasheet

Input and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.20.
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 A3NCPUP21-S3 datasheet PDF catalog A3NCPUP21-S3 PDF datasheet A3NCPUP21-S3
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 A3NCPUP21-S3 datasheet PDF catalog A3NCPUP21-S3 PDF datasheet.
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 A3NCPUP21-S3 datasheet PDF catalog A3NCPUP21-S3 PDF datasheet.
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 opperation instructions for 2~4 A3NCPUP21-S3 datasheet PDF catalog A3NCPUP21-S3 PDF datasheet. 8 channel analog output module.
Ans series has now launched a dedicated 8 channel D/A components,
Both voltage output and current output can be provided.
Inn this way, the user system to provide a higher density of D/A features,
The same method is used to maintain the same output voltage or current output A3NCPUP21-S3 datasheet PDF catalog A3NCPUP21-S3 PDF datasheet.
