32 point connector 40 pin connector for welding.Input type: DC input, positive public end / negative public end.
Input points: 16 points.
Enter the response time: 0.2ms below, below 1.5ms, 5ms below, 10ms the following.
Rated input voltage / current: DC24V/7mA.
External connection: 3 wire.
According to the external connection mode and the external equipment input and output specifications,
Choose from a rich product lineup AJ71VP21 PDF datasheet AJ71VP21
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. Input and output points: 2048 points.
Input / output data points: 2048 points AJ71VP21 PDF datasheet .
Program capacity: 30K.
Basic command processing speed (LD command) s:0.15.
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.
Modular: PLC is the basic components of a separate module AJ71VP21 PDF datasheet .
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 MITSUBISHI AJ71VP21 PDF catalog.
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 MITSUBISHI AJ71VP21 PDF catalog.
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 MITSUBISHI AJ71VP21 PDF catalog.
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 AJ71VP21 datasheet.
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 AJ71VP21 PDF datasheet . Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
