QA68B MITSUBISHI Extended substrate MITSUBISHI QA68B

Input / output points: 4096 points.
Input / output soft element points: 8192.
Program capacity: 30K step.
Basic operation speed (LD): 1.9ns.
Program memory capacity: 120KB.
Peripheral device connection port: USB, Ethernet (communication support function).
Memory card I/F:SD memory card, extended SRAM card QA68B.
Convenient processing of large capacitty data.
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 QA68B.
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 QA68B.
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 MITSUBISHI QA68B.
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.
When the index is used to modify the program repeatedly (e.g. from FOR to NEXT), the scan time can be reduced MITSUBISHI QA68B.
Support USB and RS232.
Support installed memory card.
Providing high speed communication between multiple CPU.
Shorten the fixed scan interrupt time, high precision device.
The minimum interval of the fixed period interrupt program is reduced to 100 s.
The high speed signal can be accurately obtained, which makes the contribution to the higher precision of the device MITSUBISHI QA68B.
High speed and high precision machine control by multi CPU.
By parallel processing of the linear and multi CPU high-speed communication (cycle 0.88ms) of the parallel control program, the high speed control.
Multi CPU high speed communication cycle and motion control synchronization, so it can achieve the maximization of computing efficiency.
In addition, the latest movement control CPU in performance is 2 times the previous model,
To ensure high speed and high accuracy of the machine control.Input points: servo external signal 32 points, 8 axis.
Input mode: source / drain type.
Input and output points: 32 points.
Better user experience data recording function.
Easy to record, no need to program.
Simply through the special configuration tool wizard to easily complete the settings,
The collected data can be saved in CSV format to SD storage card.
Can be effectively used to save the CSV file to facilitate the creation of a variety of reference materials,
Including daily reports, generate reports and general reports.
These data can be applied to the data analysis, tracing, etc..
To record the change of control data without missing.
Data can be collected in a time interval or in a millisecond time interval,
To record the change of the specified control data without any omission.
Therefore, in the event of failure, can quickly determine the cause, the precise action analysis.
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.
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.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
System program memory for storing system proogram,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation QA68B.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
