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 A1SJ71QC24N1-R2 Modem Function Additional Version Manual A1SJ71QC24N1-R2 User's Manual A1SJ71QC24N1-R2 ) 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 A1SJ71QC24N1-R2 Modem Function Additional Version Manual A1SJ71QC24N1-R2 User's Manual.
In short, only to understand the user, to understand the task in order to design a good man-machine interface A1SJ71QC24N1-R2 Modem Function Additional Version Manual A1SJ71QC24N1-R2 User's Manual. D-STN color / monochrome LCD man-machine interface to replace the backlight.
Applicable model: A970GOT-SB_/LB_. Output type: transistor output, drain type.
Output points: 32 points.
OFF leakage current: 0.25mA.
Output protection function.
Rated load voltage / current: DC12V/DC24V/0.5A.
External connection: 1 wire.
According to the external connection mode and the external equipment input and output specifications,
Choose from a rich product lineup.
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. 10BASE5.
PLC is introduced by the relay control technology after the development of micro processing technology,
Can be easily and reliably used for switching control.
As the analog quantity can be converted into digital quantity, the number of digital quantity is just a number of switching value,
Therefore, after the conversion of analog, PLC can also be reliable for processing control.
Because the continuous production process often has the analog quantity, the analog quantity control is sometimes called process control.
Analog quantity is not electricity, and PLC can only handle digital quantity, quantity of electricity.
All to realize the conversion between them to have the sensor, the analog quantity into a number of power.
If this power is not standard, but also through the transmitter,
The non-standard power into a standard electrical signal, such as 1-5V, 4-20mA, 0-10V, etc..
At the same time, there is also an analog input unit (A/D),
Transform these standard electrical signals into digital signals,
The analog output unit (D/A), in order to transform the digital quantity after PLC processing into analog quantity -- standard electric signal.
So the standard telecommunication number, the conversion between the number of operations to use a variety of computing.
This requires the resolution of the analog unit and the standard electrical signal.
The length of time required to execute the instruction, the length of the user''s program, the type of instruction, and the speed of the CPU execution are very significant,
Generally, a scanning process, the fault diagnosis time,
Communication time, input sampling and output refresh time is less,
The execution time is accounted for the vast majority of.
The structured text programming language uses the computer description method to describe the various kinds of relations between the various variables in the system,
Complete the required function or operation.
Most PLC manufacturers use structured text programming language similar to BASIC language, PASCAL language or C language and other advanced languages,
But in order to be convenient, the expression methods of the statement and the types of statements are simplified.
Structured text programming language features: the use of high-level language programming, you can complete the complex control operations,
Need to have a certain level of computer knowledge and programming skills,
Higher requirements for engineering designers. Poor visibility and operability.
Switching value, also known as logic, refers to only two values, 0 or 1, ON or OFF.
It is the most common control, it is the advantage of PLC control,
Is also the most basic application of PLC.
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So thhat PLC generates the corresponding switching output,
In order to make the system work in a certain order A1SJ71QC24N1-R2 Modem Function Additional Version Manual A1SJ71QC24N1-R2 User's Manual.
So, sometimes also known as the order control.
And seqquential control is divided into manual, semi-automatic or automatic A1SJ71QC24N1-R2 Modem Function Additional Version Manual A1SJ71QC24N1-R2 User's Manual.
And the control principle is decentralized, centralized and hybrid control three.
