Design any machine interface, generally have to consider the system response time, user assistance mechanism, error information processiing and command mode four aspects A1SJ71LP21.
System response time is too long to be the most users in the interactive system,
In addition to the absolute length of the response time, the user is also very concerned about the difference in response to different commands in response time,
If too wide users will be difficult to accept; user assistance mechanism should be integrated,
Avoid overlay systems that cause users to turn to a guide and have to browse a large number of irrelevant information;
Error and warning information must be selected in terms of user''s clarity and meaning,
At the same time, it should be as far as possible to provide some suggestions on the recovery of errors A1SJ71LP21 A1SJ71LP21.
In addition, when the error message is displayed, the effect is better if it is supplemented by the auditory (Bell) and visual (special color) stimulus;
Command mode is the best menu and keyboard commands, for the user to choose MITSUBISHI A1SJ71LP21. 2 axes.
2 axis linear interpolation.
Control unit: pulse, mm, inch, degree MITSUBISHI A1SJ71LP21.
Determine the location of the number of data: 400/1 axis.
40 pin connector.
Control mode: position automatic acceleration and deceleration time: 64-4999ms pulse train output.
Structured text language is a programming language that describes a program with a structured description of the text MITSUBISHI A1SJ71LP21.
It is a programming language similar to a high level language. In large and medium
Structured text is often used to describe the relationship between the various variables in the control system based on the PLC system.
Mainly used for other programming languages more difficult to achieve the user program.
Sequential function flow chart language is designed to satisfy the sequential logic control.
The process of sequential process action is divided into steps and transformation conditions,
According to the transfer condition, the control system is distributed in the function flow sequence,
Step by step according to the sequence of actions.
Each step represents a control function, represented by the box.
In the box, the ladder logic is used to complete the task of the corresponding control function.
This programming language makes the program structure clear and easy to read and maintain,
Greatly reduce the programming workload, shorten the programming and debugging time.
Used in the system of the size of the school, procedures for more complex occasions.
Sequence function flow chart programming language features: to function as the main line, in accordance with the functional flow of the order of distribution, clear, easy to understand the user program,
Avoid the defect of ladder diagram or other languages,
At the same time, the use of ladder language to avoid the use of ladder programming,
Due to the complicated mechanical interlock, the structure of the user program is complex and difficult to understand,
User program scan time is also greatly reduced.
A1SD75 series components show MITSUBISHI in manufacturing and design CNC,
Integrated technical experience in the aspects of frequency converter, servo system and PLC.
These components have a wealth of features that are sufficient to meet the highest requirements in the application of positioning control.
Up to 3 axis linkage operation,
In low cost motion control applications, this component can be used to control the operation of a multi - to 3 axis, which can be used to account for only one slot.
10Mbps transmission speed, the computer as the support of the flexible manufacturing system at the plant level, the requirements of more and more data flow,
High transmission speed can be guaranteed to increase the amount of transmitted data while maintaining the minimum time to transfer and receive data between programmable controllers.
The response time of PLC is the interval between the time of the change of the external output signal of the PLC and the time of the change of the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the use of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on.
This phenomenon is called the I/O delay time effect.
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 ssystem work in a certain order A1SJ71LP21.
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.
