Input and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:1.0.
AnNCPU command processing time and ACPU compare to 10-20% high speed processing.
User program storage capacity: it is a measure of how much the user application can store the number of indicators MITSUBISHI ID Interface Module User's Manual.
Usually in words or K words as units
AD35ID1 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.
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 MITSUBISHI ID Interface Module User's Manual.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance. Three slots in one side.
Power supply unit.
Q4AR duplex system.
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order MITSUBISHI ID Interface Module User's Manual AD35ID1 User's Manual.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic AD35ID1 User's Manual.
And the control principle is decentralized, centralized and hybrid control three.
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 AD35ID1 User's Manual.
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 / ouutput hysteresis phenomena, i AD35ID1 Manual. e., the input / output response delay.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program tto do the compiler to compile the process of interpretation MITSUBISHI ID Interface Module User's Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
