RS-422 connection (QnA/A/FXCPU direct connection, computer connection, micro computer connection).
No clock function.
Applicable models: A985 (-V) /975/970/960GOT. Input and output points: 512 points.
Input / output data points: 512 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0 AJ35T-OPB-P1 PDF catalog. 20.
Optical data communication line.
Each scanning process. Focus on the input signal sampling AJ35T-OPB-P1 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 AJ35T-OPB-P1 PDF catalog.
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 AJ35T-OPB-P1 PDF catalog. 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 Modular PDF catalog. PLC to store instructions and data in words.
General logical operation instructions each account for 1 words. Timer / counter,

The popularization and application of PLC programming has been developed rapidly in our country,
It has been widely used in all kinds of mechanical equipment and production process of electrical control devices,
All walks of life have emerged a large number of application of PLC transformation of the results of the equipment.
Understand the working principle of PLC, have the ability to design, debug and maintain the PLC control system,
Has become the basic requirements of modern industry for electrical technicians and engineering students.
Switching value, also known as logic, refers to only two values, 0 or 1, ON or OFF.
It is the most common control, it is the advantage of PLC control,
Is also the most basic application of PLC.
Structured text language is a programming language that describes a program with a structured description of the text.
It is a programming language similar to a high level language. In large and medium-sized PLC systems, structured text is often used to describe the relationship between the variables in the control system.
Mainly used for other programming languages more difficultt to achieve the user program AJ35T-OPB-P1 PDF datasheet.
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 CCPU AJ35T-OPB-P1 PDF catalog.
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.
