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 AC50TB datasheet PDF catalog AC50TB PDF datasheet
AC50TB
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 AC50TB datasheet PDF catalog AC50TB PDF datasheet.
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 AC50TB datasheet PDF catalog AC50TB PDF datasheet. A1S68TD is a 8 channel thermocouple input module,
It can receive almost any type of thermocouple input,
Using Ans CPU A1S68TD system can meet the various requirements of process control applications,
Also has the advantages of all aspects of the ANs can provide.
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 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 thee 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 usse of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on AC50TB datasheet PDF catalog AC50TB PDF datasheet AC50TB datasheet PDF catalog AC50TB PDF datasheet.
This phenomenon is called the I/O delay time effect.
