RS-232 2 channel.
Transfer speed: 0.3-19.2kbps.
CPU will be stored in the working data memory or in the input image register.
And then combine the data and the program with CPU.
And then output to the output interface, control the external drive.
Semiconductor circuit with memory function.
System program memory and user memory.
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
5 slots; requires 1 AnS series PLC power modules;
Used to install large AnS series PLC module.
Base plate of AnS series PLC.
QA1S series PLC 5 slot main substrate.
AnS series of modules can be installed. Enter 64 points.
Response time: 16ms.
16 pin connector.
Output 64 points.
Response time: 16ms MITSUBISHI A1SJ71QC24-R2.
32 pin connector dynamic input and output data.
PLC is introduced by the relay control technology after the development of micro processing technology,
Can be easily and reliably used for switching control A1SJ71QC24-R2
As the analog quantity can be converted into digital quantity, the number of digital quantity is just a number of switching value,
Therefore, after the conversion of analog, PLC can also be reliable for processing control MITSUBISHI A1SJ71QC24-R2.
Because the continuous production process often has the analog quantity, the analog quantity control is sometimes called process control.
Analog quantity is not electricity, and PLC can only handle digital quantity, quantity of electricity.
All to realize the conversion between them to have the sensor, the analog quantity into a number of power.
If this power is not standard, but also through the transmitter,
The non-standard power into a standard electrical signal, such as 1-5V, 4-20mA, 0-10V, etc MITSUBISHI A1SJ71QC24-R2. .
At the same time, there is also an analog input unit (A/D),
Transform these standard electrical signals into digital signals,
The analog output unit (D/A), in order to transform the digital quantity after PLC processing into analog quantity -- standard electric signal.
So the standard telecommunication number, the conversion between the number of operations to use a variety of computing.
This requires the resolution of the analog unit and the standard electrical signal. PLC station distance: 500M.
Cable type: coaxial cable.
The function of the MELSECNET interface module is to connect the main CPU PLC to the MELSECNET data communication system.
As long as the switch on the component to set,
Can determine the CPU PLC is as the main station or in situ station.
There are two modules available for selection: one is the connection of the optical cable network and the network of the coaxial cable.
For a ANSCPU, up to only a piece of interface components can be inserted, A2ASCPU can be inserted 2.
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.
The instruction list programming language is a programming language similar to assembly language mnemonic,
As well as assembly language by the operation code and the number of operations.
In the case of the computer for the PLC handheld programmer compile user program.
At the same time, the programming language of the instruction list corresponds to the ladder diagram programming language,
In PLC programming software can be converted to each other. Figure 3 is the instruction sheet corresponding to the ladder diagram of figure 2PLC.
The characteristics of instruction table programming language is used to represent mnemonic operation function,
Easy to remember, easy to grasp;
In the handheld programmer on the keyboard using the mnemonic representation, easy to operate, can be programmed in computer;
There is a one-tto-one correspondence between the ladder diagram and the ladder diagram A1SJ71QC24-R2 A1SJ71QC24-R2. Its characteristics are basically consistent with the ladder diagram language.
