Input and output points: 512 points.
Input / output data points: 8192 points.
Program capacity: 28k.
Basic command processing speed (LD command) S:0.075.
PLC in the program execution stage: according to the order of the user program order to store the order of each instruction,
After the corresponding operation and processing, the result is written to the output status register,
The contents of the output status register are changed with the execution of the program MITSUBISHI Q25HCPU Reference Manual Q25HCPU
Output refresh phase: when all instructions are executed,
The output status register is sent to the output latch in the output refresh stage,
And through a certain way (relay, transistor or transistor) output, drive the corresponding output equipment MITSUBISHI Q25HCPU Reference Manual. Program capacity: 124 K step.
Input / output points: 4096 points.
Number of input and output elements: 8192.
Processing speed: 0.034 s.
Program memory capacity: 496 KB.
Support USB and RS232.
CPU module expansion standard RAM (max 8MB).
Can be used with the SD memory card at the same time.
Continuous access file register.
Ultra high speed processing, production time is shortened, better performance MITSUBISHI Q25HCPU Reference Manual.
As applications become larger and more complex, it is necessary to shorten the system operation cycle time.
The operation period can be shortened by the super high basic operation speed 1.9ns.
In addition to achieve in the past with the control of single-chip high-speed control,
The system performance can be improved by reducing the total scan time,
To prevent any possible performance bias.Battery replacement.
Initial voltage 3.0V.
Replacement of large capacity battery module without cable.
Current capacity: 18000mAh.
Service life: 5 years.
Outline dimension: 98*55.2*87mm.5 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.
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.
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 outpput mode Q25HCPU Manual.
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 Q25HCPU Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
