Compact flash memory card.
Capacity: 2GB bytes. 8 slots.
Requires 1 power modules.
Used to install the old section of the large A series PLC module.
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order MITSUBISHI Q172CPUN Manual Q172CPUN
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh MITSUBISHI Q172CPUN Manual .
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 MITSUBISHI Q172CPUN 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.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.8 slots.
Extended substrate.
Double power supply mode power supply redundancy system.
Used to install Q series modules.
Reduce system downtime recovery time.
With a simple operation, you can back up all the data in the CPU to the memory card.
Through regular backup, can be the latest parameters, procedures, etc. to save the storage card.
In the event of a CPU failure, after the replacement of CPU, can be a simple operation,
Restore the system by using the data storage card in advance.
Therefore, it is not necessary to spend time to manage the backup data, but also can shorten the recovery time of the system shutdown.
Wider application range, more advanced.
Leading in the era of the Q series CPU products.
Q series CPU products a wide range of applications,
Provide programmable controller, process, redundancy, C language, movement, manipulator, CNC all kinds of CPU,
In order to meet the needs of various control Q172CPUN Programming Manual.
Through the multi CPU configuration, can be based on the use of the scale, purpose,
Construction of the best system to meet the requirements of all kinds oof control Q172CPUN Programming Manual.
In addition, the high reliability system can be constructed by the redundant system,
Even if a fault occurs, the system can continue to run.
