The external model design model of creating the system function is mainly to consider the data structure, the overall structure and the process description of the software,
The interface design is usually only used as accessories, only on the user''s situation (including age, gender, mental status, education level, personality, ethnic background and etc AJ71QE71N-B5T datasheet PDF catalog AJ71QE71N-B5T PDF datasheet AJ71QE71N-B5T ) to understand, to design an effective user interface;
According to the user model of the future system of the end user (for short),
In the end, it is consistent with the system image (external characteristic) of the system after the system is realized,
Users can be satisfied with the system and be able to use it effectively;
When the user model is established, the information given by the system should be considered,
System mapping must accurately reflect the syntax and semantic information of the system AJ71QE71N-B5T datasheet PDF catalog AJ71QE71N-B5T PDF datasheet.
In short, only to understand the user, to understand the task in order to design a good man-machine interface AJ71QE71N-B5T datasheet PDF catalog AJ71QE71N-B5T PDF datasheet. Interface: RS232C.
Transmission distance: 15 meters.
A1SJ71UC24-R2/R4/PR computer communication components can be relied on external intelligent devices such as computers and PLC for communication, the components are as follows:
Full / half duplex transmission,
4 special communication protocols,
No protocol and bidirectional mode,
Protocol selection switch function,
The optional baud rate, the highest 19.2K,
Since the echo diagnostic test. 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.
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.
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 pheenomena, i AJ71QE71N-B5T datasheet PDF catalog AJ71QE71N-B5T 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 AJ71QE71N-B5T datasheet PDF catalog AJ71QE71N-B5T PDF datasheet.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
