Terminal row for A2CAnS, QnAS bus connection, the reader to write program 2 channel connection.
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.
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 A3NMACA0-UL Manual A3NMACA0-UL User's Manual A3NMACA0-UL
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 A3NMACA0-UL Manual A3NMACA0-UL User's Manual.
This phenomenon is called the I/O delay time effect. 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 A3NMACA0-UL Manual A3NMACA0-UL User's Manual.
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 control scheme is simple and easy: functiion 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 A3NMACA0-UL Manual A3NMACA0-UL User's Manual A3NMACA0-UL Manual A3NMACA0-UL User's Manual.
