The main unit of the AS-i system
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 A1SJ72QLP25 PDF A1SJ72QLP25
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 A1SJ72QLP25 PDF.
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. 16 channels.
Thermocouple input A1SJ72QLP25 PDF.
38 point terminal station.

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: 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 A1SJ72QLP25 Manual A1SJ72QLP25 Reference Manual .
