MITSUBISHI A9GT-QCNB User's Manual PDF

A pack of 10.
Applicable models:
AJ65VBTCE - -8 - type.
AJ65VBTCE - -16 - type. Output points: 16 points.
Voltage: DC5/12V.
Output type: Sink type.
Response time: 1ms A9GT-QCNB PDF.
8 points / a common end.
20 point terminal station.
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 A9GT-QCNB
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 A9GT-QCNB PDF.
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 A9GT-QCNB PDF.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive MITSUBISHI User's Manual.
Different series of different models of PLC has different performance, aapplicable occasions also have different emphasis,
Price also has a greater difference A9GT-QCNB Manual. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC MITSUBISHI User's 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.
Read only memory. Manufacturers use, content can not be changed, power does not disappear MITSUBISHI User's Manual. AnS, QnAS bus connection, the reader to write program 2 channel connection.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register.
And then combine the data and the program with CPU.
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive.
The response time of PLC is the interval between the time of the change of the external output signal of the PLC and the time of the change of the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the usse of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on A9GT-QCNB Manual A9GT-QCNB User's Manual.
This phenomenon is called the I/O delay time effect.
