MELSECNET/B (Master / local station).
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program.
Procedures to meet the requirements of system control as the main line,
Write one by one to achieve the control function or the sub task of the program,
Gradually improve the functions specified by the system AJ35PTC-CNV-GI PDF datasheet AJ35PTC-CNV-GI
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc AJ35PTC-CNV-GI PDF datasheet . . Program memory capacity: 8k.
Input / output points: maximum 256 points.
With base plate and power supply.
PLC is the use of " sequential scanning, and constantly circulating " way to work.
That is, in the operation of CPU, PLC according to the user according to the control requirements of the coexistence of the user in the memory of the program,
According to the instruction sequence number (or address number) for periodic cyclic scan, such as no jump instruction,
From the first instruction to the user program execution sequence one by one, until the end of the program,
And then return to the first command, start the next round of the new scan, in the process of each scan,
Also complete the sampling of the input signal and the output status of the refresh and other work AJ35PTC-CNV-GI PDF datasheet MITSUBISHI AJ35PTC-CNV-GI PDF catalog MITSUBISHI AJ35PTC-CNV-GI PDF catalog.
With the rapid development of microprocessor, computer and digital communication technology,
Computer control has been extended to almost all industrial fields.
Modern society requires manufacturing to respond quickly to market demand,
Production of small quantities, multi varieties, multi specifications, low cost and high quality products,
In order to meet this requirement,
Production equipment and automatic production line control system must have high reliability and flexibility,
PLC programming is to comply with the requirements of the emergence of it is based on a microprocessor based general industrial control device MITSUBISHI AJ35PTC-CNV-GI PDF catalog.
PLC programming is a digital computing operation of the electronic system,
Designed for applications in industrial environments.
It uses programmable memory,
An instruction used to perform logical operations,, sequence control, timing, counting and arithmetic operations in its internal storage,
And through the digital, analog input and output, control of various types of machinery or production process AJ35PTC-CNV-GI datasheet.
Programmable controlller and related equipment,
Should be easy to make the industrial control system to form a whole, easy to expand the principle design of its functions AJ35PTC-CNV-GI PDF datasheet .
