Structured text language is a programming language that describes a program with a structured description of the text.
It is a programming language similar to a high level language AJ71LP21G Manual AJ71LP21G Reference Manual . 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 AJ71LP21G
Mainly used for other programming languages more difficult to achieve the user program.
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 AJ71LP21G Manual AJ71LP21G Reference Manual .
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 AJ71LP21G Manual AJ71LP21G Reference Manual . Poor visibility and operability. Output type: transistor source.
Output points: 16 points.

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 andd 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 AJ71LP21G Manual AJ71LP21G Reference Manual .
So, sometimes also known as the order control.
And seqquential control is divided into manual, semi-automatic or automatic AJ71LP21G Manual AJ71LP21G Reference Manual .
And the control principle is decentralized, centralized and hybrid control three.
