47 point terminal station.
How to determine the input / output device of MITSUBISHI plc.
According to the control requirements of the system,
All input devices and output devices rrequired for the determination of the system,
To determine the input / output device related to the MITSUBISHI PLC,
To determine the I/O PLC points A2ACPU A2ACPU.
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 A2ACPU.
Input and output points: 512 points.
Input / output data points: 512 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.20.
Each scanning process. Focus on the input signal sampling MITSUBISHI A2ACPU. 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 MITSUBISHI A2ACPU.
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 MITSUBISHI A2ACPU.
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 measure of how much the user application can store the number of indicators.
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 logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4. Input voltage range: AC100-120V/AC200-240V.
Output voltage: DC5/24V.
Output current: 2/1.5A.
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 occcasions also have different emphasis,
Price also has a greater difference A2ACPU. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC.
