The A1SD61 high speed counting module can receive up to 50KHz of pulse signals,
The signal can be counted when the input pulse is rising and the falling time is greater than 500.
This component has a 32 bit signed binary count range,
Counter can be preset, can also use the external signal or the control program will stop counting A2ACPU PDF catalog.
Structured text language is a programming language that describes a program with a structured description of the text A2ACPU
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 A2ACPU PDF catalog.
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 A2ACPU PDF catalog.
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 MITSUBISHI CPU unit PDF catalog.
Used in the system of the size of the school, procedures for more complex occasions MITSUBISHI CPU unit PDF catalog.
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 MITSUBISHI CPU unit PDF catalog. Output type: transistor source / drain type.
Output points: 8 points.
Load voltage: DC5/12/24/48.
Load current: 2A.
Connection mode: terminal row.
Common public end points: 1.
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 combinatioon 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 A2ACPU PDF datasheet.
So, sometimes also known as the order control.
And seqquential control is divided into manual, semi-automatic or automatic A2ACPU PDF catalog.
And the control principle is decentralized, centralized and hybrid control three.
