AJ65ABTP - - - type.
AJ65VBCU- - type.
AJ65SBT-CLB type. JEMANET (OPCN-1) interface unit master station.
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 use of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on A1SJ71QLP21GE PDF datasheet A1SJ71QLP21GE
This phenomenon is called the I/O delay time effect.
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 A1SJ71QLP21GE PDF datasheet.
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. A pack of 10.
Applicable models:
AJ65VBTS - - - type.
AJ65VBTCE - - - type A1SJ71QLP21GE PDF datasheet.
AJ65VBTCU - - - type.
AJ65ABTP - - - type.
AJ65VBCU- - type. CPU connection program input device.
ACPU use. Input and output points: 512 points.
Input / output data points: 512 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.20.
Coaxial data communication line function.
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.
User program storage capacity: it is a measure off how much the user application can store the number of indicators A1SJ71QLP21GE PDF catalog.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General llogical operation instructions each account for 1 words A1SJ71QLP21GE PDF catalog. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
