Available network: 10BASE5.
Max / total distance: 500/2500M.
Used to hang ANS series PLC to ethernet.
There are two kinds of hanging network modules: A1SJ71E71-B2-S3 and A1SJ71E71-B5-S3 respectively corresponding to 10BASE2 and 10BASE5,
So that the vast majority of installed cable can continue to use.
JEMANET (OPCN-1) interface unit from the station.
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 A1SJ71E71-B5-S3
A1SJ71E71-B5-S3
This phenomenon is called the I/O delay time effect.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register.
And then combine the data and the program with CPU A1SJ71E71-B5-S3.
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive. Output type: transistor drain.
Output points: 64 points.
Load voltage: DC12/24.
Load current: 0.1A.
Connection mode: terminal row.
Common public end points: 32.
Structured text language is a programming language that describes a program with a structured description of the text A1SJ71E71-B5-S3.
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.
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.
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 convenieent, the expression methods of the statement and the types of statements are simplified A1SJ71E71-B5-S3.
Structured text programming language features: the use of high-level language programming, you can complete the complex control operations,
Needd to have a certain level of computer knowledge and programming skills,
Higher requirements for engineering designers A1SJ71E71-B5-S3. Poor visibility and operability.
