Omron PLC/ PLC control panel for Constant pressure water supply,water pump,boiler
Programmable logic controller is a kind of industrial control computer, the hardware structure is basically the same with the microcomputer, the basic structure is:
First, the Omron PLC control panel power
Programmable logic controller power supply in the entire system plays a very important role.
If not a good, reliable power supply system is not working,
Therefore, the programmable logic controller manufacturers of power supply design and manufacture also attaches great importance.
General AC voltage fluctuations in the +10% (+15%) range, you can not take other measures to the PLC directly connected to the AC power grid
Second, the central processing unit (CPU)
Central processing unit (CPU) is the programmable logic controller of the control center.
Which receives and stores the user program and data inputted from the programmer in accordance with the function assigned by the programmable logic controller system program;
Check the status of the power supply, memory, I / O and watchdog timer and can diagnose syntax errors in the user program.
When the programmable logic controller is put into operation,
First of all, it scanned the way to receive the state of the input devices and data, and were deposited into the I / O image area,
And then from the user program memory one by one to read the user program, after the interpretation of the order according to the provisions of the instruction logic or arithmetic operations results into the I / O image area or data register.
After all the user program execution is complete,
Finally, the I / O image of the output state of the output register or the data transfer to the corresponding output device, so the cycle run until the stop running.
In order to further improve the reliability of programmable logic controllers, in recent years, large-scale programmable logic controller also uses dual CPU constitute a redundant system, or a three-CPU voting system. In this way, even if |
