I/O points is an important indicator of PLC.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest A951GOT-QSBD-M3.
The input and output points and types of PLC should bbe determined according to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point A951GOT-QSBD-M3.
Taking into account the future adjustment and expansion,
In general should be estimated on the total number of points plus the amount of spare 20%~30%.
When the programmer input programinto the user program memory,
Then CPU according to the function of the system (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program A951GOT-QSBD-M3.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage MITSUBISHI A951GOT-QSBD-M3.
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is disconnected from the load MITSUBISHI A951GOT-QSBD-M3.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action. Program memory capacity: 8k.
Input / output points: maximum 256 points.
With base plate and power supply MITSUBISHI A951GOT-QSBD-M3.
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.
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.
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.
Programmable controller 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.

China is the world''s biggest market for human machine interface,
But it is not the highest sales market in the world,
This shows that the low-end user interface in China has a large share of.
In recent years, the rapid development of national brands, to take a low price and other strategies, is a massive attack on the low end of the market,
Has occupied the dominant position in the low-end market, has won the recognition of the majority of users.
International brands are also gradually developing its economic products, in order to seize the share of the low-end market A951GOT-QSBD-M3.
Therefore, in the low-end market steady,
The overall performance of the domestic human machine interface manufacturers showing a rapid growth of the state.
