Functional block diagram language is a kind of PLC programming language, which is similar to digital logic circuit A3UCPU PDF.
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 complex control logic,
Because the function module diagram can clearly express the function relation, the programming debugging time is greatly reduced A3UCPU PDF A3UCPU PDF A3UCPU MITSUBISHI PLC program simulation debugging
The basic idea of program simulation debugging is,
In order to facilitate the form of simulation to generate the actual state of the scene,
Create the necessary environmental conditions for the operation of the program MITSUBISHI Programming Manual.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation. Input points: 32 points.
Voltage: AC200 ~ 240V.
Current: 12mA.
Response time: 25ms.
32 points / a common end.
38 point terminal station MITSUBISHI Programming Manual.
CE certification.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as thee user program to do the compiler to compile the process of interpretation A3UCPU Manual .
Read only memory. Manufacturers use, content can not be changed, power does not disappear MITSUBISHI Programming Manual.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the component image register are changed with the change of the execution of the program A3UCPU Programming Manual.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to thhe adoption of centralized sampling A3UCPU Manual .
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
