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 AJ71ME81 PDF datasheet . 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 AJ71ME81
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 AJ71ME81 PDF datasheet .
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 AJ71ME81 PDF datasheet . Poor visibility and operability MITSUBISHI AJ71ME81 PDF catalog. Multiple CPU units for A3VTS multiplex system.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way MITSUBISHI AJ71ME81 PDF catalog. Easy maintenance.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words MITSUBISHI AJ71ME81 PDF catalog.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current annd voltage AJ71ME81 datasheet.
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is discoonnected from the load AJ71ME81 PDF datasheet .
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
