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 A2NCPU PDF.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation A2NCPU 16 channels.
Input: DC-10 ~ 10V, DC-20 ~ 20mA.
Output (resolution): 0 ~ 4000, 0 ~ 8000, 0 ~ 12000.
38 point terminal station.
Analog I/P multiplexing unit.
Detailed analysis of the process and work characteristics of the controlled object,
To understand the coordination between the controlled object machine, electricity and liquid,
The control requirements of the controlled object for MITSUBISHI PLC control system are put forward,
Determine the control program, to develop a design task book A2NCPU PDF A2NCPU PDF.
How to determine the input / output device of MITSUBISHI plc.
According to the control requirements of the system,
All input devices and output devices required for the determination of the system,
To determine the input / output device related to the MITSUBISHI PLC,
To determine the I/O PLC points MITSUBISHI Programming Manual A2NCPU Manual . Input and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Optical data communication line function (GI cable).
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process MITSUBISHI Programming Manual. 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 MITSUBISHI 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 the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
User program storage capacity: it is aa measure of how much the user application can store the number of indicators A2NCPU Programming Manual.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General llogical operation instructions each account for 1 words A2NCPU Manual . Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
