How to determine the input / output device of MITSUBISHI plc A73CPUR21-S3 PDF.
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 A73CPUR21-S3
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 A73CPUR21-S3 PDF. TFT color LCD touch screen to replace the backlight.
Applicable model: A985GOT-V. Pulse input: DC input.
Default input: DC input.
Count range: 0~16777215 A73CPUR21-S3 PDF.
Number of stations: 4 stops.
Station type: remote equipment station.
Configuration of master / local station,
In addition to the other site network with different CC-Link in addition to the main station and the remote station configuration can also be the main station and the local station configuration MITSUBISHI Programming Manual.
A local PLC can communicate with the master station PLC and other remote workstations. Input and output points: 4096 points.
Input / output data points: 8192 points.
Program capacity: 30K.
Basic command processing speed (LD command) s:0.15.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing too form a single overall called the host or the basic unit, small, ultra small PLC using this structure MITSUBISHI Programming Manual A73CPUR21-S3 Manual .
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way MITSUBISHI Programming Manual. Easy maintenance.
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.
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 a measuure of how much the user application can store the number of indicators A73CPUR21-S3 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 A73CPUR21-S3 Manual . Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
