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 Q25HCPU Application Functions Manual Q25HCPU Programming Manual
Q25HCPU
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.
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 Q25HCPU Application Functions Manual Q25HCPU Programming Manual.
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 Q25HCPU Application Functions Manual Q25HCPU Programming Manual.
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.Input: 4 channels.
Platinum resistance (Pt100; JPt100; Ni100).
Conversion speed: 40ms/1 channel.
18 point terminal.
Isolation between channels.
Platinum thermal resistance (Pt100, JPt100).
Nickel thermal resistance (Ni100).
Shedding detection function.
Conversion speed: 320ms/8 channel.
Inter channel isolation.
40 pin connector.
Most suitable for process control of isolated analog modules.
Temperature data can be collected by connecting thermocouple / thermal resistance.
Products can choose multi-channel (8 channel) input type and channel isolation type.
Customers can choose the most suitable model according to the intended use.
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.
Auto backup key data
Save the program and parameter files automatically to the program memory (ROM Flash) without using the backup battery,
To prevent the loss of the program and the parameters due too forgetting to replace the battery Q25HCPU Application Functions Manual Q25HCPU Programming Manual.
In addition, the soft component data and other important data can be backed up to the standard ROM,
In order to avoid during the long holiday and otther planned downtime,
The data is lost due to battery depletion Q25HCPU Application Functions Manual Q25HCPU Programming Manual.
The next time the power is turned on, the backup data will be automatically restored.
