Program memory capacity: 8k.
Input / output points: maximum 256 points.
With base plate and power supply.
With the rapid development of microprocessor, computer and digital communication technology,
Computer control has been extended to almost all industrial fields.
Modern society requires manufacturing to respond quickly to market demand,
Production of small quantities, multi varieties, multi specifications, low cost and high quality products,
In order to meet this requirement,
Production equipment and automatic production line control system must have high reliability and flexibility,
PLC programming is to comply with the requirements of the emergence of it is based on a microprocessor based general industrial control device MITSUBISHI A1SD75P2 MITSUBISHI A1SD75P2 A1SD75P2
PLC programming is a digital computing operation of the electronic system,
Designed for applications in industrial environments.
It uses programmable memory,
An instruction used to perform logical operations, sequence control, timing, counting and arithmetic operations in its internal storage,
And through the digital, analog input and output, control of various types of machinery or production process MITSUBISHI A1SD75P2.
Programmable controller and related equipment,
Should be easy to make the industrial control system to form a whole, easy to expand the principle design of its functions. 8 channel analog input module.
This is a high density of 8 channel A/D components,
Can receive voltage and current input, with the installation of the inside of the cover plate switch,
The input type and range of each channel can be set up according to the application requirements:
12 bit resolution,
Automatic drift correction function,
0.5msec/1 channel,
-10-0-10V or 0-20mA input. Up to controlled I/O points: 8 point I/O combination module, up to 128 points.
Use any I/O module, up to 64 points.
Flexible system configuration; each remote I/O component is controlled by the I/O point to remain sufficiently low,
So in the installation of control equipment where only the I/O point is not wasted.
At the same time, it is not required to have the terminal resistance and the T - type branch to obtain the maximum flexibility.
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. 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.
Functional block diagram language is a kind of PLC programming language, which is similar to digital logic circuit.
The function module is used to represent the function of the module,
Different function modules have different functions.
Functional module figure programming language features: functional block diagram programming language is characterized by a functional module for the unit,
Analysis and understanding of the conttrol scheme is simple and easy: function module is to use graphical form of expression,
Intuitive, for a digital logic circuit based on the design of the staff is very easy to master the programming;
Control system with complex scale and coomplex control logic,
Because the function module diagram can clearly express the function relation, the programming debugging time is greatly reduced A1SD75P2 A1SD75P2.
