MITSUBISHI AJ71BR11 Reference Manual PDF

Input and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.20 AJ71BR11 PDF.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure AJ71BR11
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh AJ71BR11 PDF.
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 AJ71BR11 PDF.
The contents of the component image register are changed with the change of the execution of the prrogram AJ71BR11 Manual .
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 MITSUBISHI Reference Manual .
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words MITSUBISHI Reference Manual . PLC to store instructions and data in words.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4. MELSECNET (II).
Optical fiber loop. Ontology CPU installation to P-ROM program device MITSUBISHI Reference Manual . RS422 interface conversion cable packageHardware implementation is mainly to control cabinet and other hardware design and field construction.
Design control cabinet and the operating table and other parts of the eleectrical wiring diagram and wiring diagram AJ71BR11 Reference Manual .
Electrical interconnection diagram of each part of the design system.
According to the construction drawings of the site wiring, and carry out a detailed inspection.
Because the program deesign and hardware implementation can be carried out at the same time,
So the design cycle of the MITSUBISHI PLC control system can be greatly reduced AJ71BR11 Manual .
