Input and output points: 512 points.
Input / output data points: 8192 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 A1SJ72T25B
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 MITSUBISHI A1SJ72T25B. 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 MITSUBISHI A1SJ72T25B.
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. Drive: MR-H_ACN series SSC-NET compatible AC servo.
Rated output: 0.2KW.
The servo controller can easily transfer the operation module and the field bus module through the automation interface,
At the same time using different fieldbus modules to achieve different control modes (RS485, RS232, optical fiber, InterBus, ProfiBus),,
And the contrrol mode of general inverter is single A1SJ72T25B.
The servo controller is directly connected with a rotary transformer or an encoder, which forms a closed loop of speed and displacement control.
The general inverter can only form an open loop cconntrol system A1SJ72T25B.
Servo controller of the control parameters (such as steady-state accuracy and dynamic performance) is better than the general inverter.
