Cable length: 1 meters.
The connection between the A0J2HCPU power supply unit (A0J2-PW) and the GOT. Program memory capacity 14K.
Input and output points to the maximum 512 points.
A scan cycle of PLC must pass through three stages: input sampling, program execution and output refresh.
PLC in the input sampling phase: first of all, in order to scan the sequence of all existing input latches in the input terminal of the state or input data read,
And write it into the corresponding input status register,
Refresh the input, then close the input port, enter the program execution stage A0J2-C214-S1 datasheet PDF catalog A0J2-C214-S1 PDF datasheet A0J2-C214-S1 8 slots.
To install the power supply.
For QnA/A series.
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 A0J2-C214-S1 datasheet PDF catalog A0J2-C214-S1 PDF datasheet.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three A0J2-C214-S1 datasheet PDF catalog A0J2-C214-S1 PDF datasheet.
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 pphenomena, i A0J2-C214-S1 datasheet PDF catalog A0J2-C214-S1 PDF datasheet. 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 A0J2-C214-S1 datasheet PDF catalog A0J2-C214-S1 PDF datasheet.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
