MITSUBISHI Q12DCCPU-V User's Manual Q12DCCPU-V Function Explanation, Program Fundamentals Manual

GI-62.5/125 optical cable.
Double ring.
PLC to PLC network (control station / common station) / remote I/O net (remote master station).Input points: servo external signal 32 points, 8 axis.
Input mode: source / drain type.
Input and output points: 32 points.
Convenient processing of large capacity data Q12DCCPU-V User's Manual.
In the past can not achieve the standard RAM and SRAM card file register area of continuous access,
The boundary of each area should be considered in programming Q12DCCPU-V
The SRAM 8MB extension card is installed in the high speed universal QCPU,
Standard RAM can be used as a continuous file register,
Capacity up to 4736K words, thus simplifying the programming.
Thus, even if the memory space of the soft element is insufficient,
Can also be installed by the expansion of SRAM card, easy to extend the file register area Q12DCCPU-V User's Manual.
The address register is extended to 32 bits, which can be programmed to go beyond the traditional 32K word,
And to achieve the extension to the file register to all regions of the file register.
In addition, the processing speed of the index modification plays an important role in the efficient operation of structured data (array),
The speed has been improved Q12DCCPU-V User's Manual.
When the index is used to modify the program repeatedly (e.g. from FOR to NEXT), the scan time can be reduced.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 output mode Q12DCCPU-V 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 Q12DCCPU-V Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
