MITSUBISHI Q02PHCPU PROGRAMMING Guide Book PLC Structured Text(ST) Manual

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 Q02PHCPU Manual .
So, sometimes also known as the order control Q02PHCPU
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 Q02PHCPU 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 Q02PHCPU 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 MITSUBISHI PLC Manual .
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 MITSUBISHI PLC Manual .
Read only memory. Manufacturers use, content can not be changed, power does not disappear.GI-62.5/125 optical cable.
Double ring.
PLC to PLC network (control station / common station) / remote I/O net (remote master station).nput / output points: 1024 points MITSUBISHI PLC Manual .
Number of input and output elements: 8192.
Program capacity: 10 K step.
Processing speed: 0.08 s.
Program memory capacity: 40 KB.
Support USB and RS232.
Unable to install memory card.
Ultra high speed processing, production time is shortened, better performance.
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.
High speed and high precision data processing.
The processing speed of the rreal number (floating point) arithmetic has been greatly improved,
Addition instruction reached 0 Q02PHCPU PROGRAMMING Guide Book. 014 mu s,
Therefore, it can support the request of high-speed, high-precision processing data processing.
In addition, the new additioon of double precision floating point arithmetic instructions,
Simplify the programming, reduces the computational error when executing complex formula Q02PHCPU Manual .
