ABB PFRA101 sensor

ABB PFRA101 sensor

ABBPFRA1011. Compared with the serial port server on the market, Direct-Net specially adds the setting parameters, which is more flexible than the serial port server on the market. It can set the relevant parameters according to the transmission byte length and response speed in the industrial control field.
2. Only add Direct-Net serial port server on the traditional PLC control system, and use the original company’s internal network cabling to save you hardware costs.
3. Install the virtual serial port software on the server side without any changes to the original traditional control software. Reduce the difficulty and cost of development.
4. It can be connected to a server compatible with the original traditional system.
PFRA1015. The transformed system can be connected to the Internet through a router.

PLC control system, Programmable Logic Controller, is a programmable logic controller. It is a digital operation electronic device designed for industrial production. It uses a class of programmable memory, which is used to store programs, execute logic operations, timing, counting and arithmetic operations and other user-oriented instructions, and control various types of machinery or production processes through digital or analog input/output. It is the core part of industrial control.
Since the introduction of Programmable Logic Controller (PLC) in the United States in the 1960s to replace the traditional relay control device, PLC has developed rapidly and has been widely used around the world. The functions of PLC are also continuously improved.
With the continuous development of computer technology, signal processing technology, control technology and network technology and the continuous improvement of user demand, PLC has added analog processing and motion control functions on the basis of switching value processing. Now PLC is no longer limited to logic control, but also plays a very important role in the fields of motion control, process control, etc.
PLC is equivalent to the brain of the machine, and the program we compile is equivalent to the knowledge and rules that people hold. The machine is equivalent to the human body, which is used to perform various actions of PLC. Electricity, gas and liquid are equivalent to human muscles and nerves. The PLC sends instructions and transmits energy to the machine through electricity, gas and liquid, and the machine executes.
The sensor feeds back the external situation to the PLC, which is equivalent to the eyes and nose of a person, and then feeds back the external things to the brain.
Take a person or an animal for example, PLC is the brain, and the combination of PLC and machine is equivalent to the combination of human brain and body, but the program in human brain is much more complex than PLC, but the sensitivity and accuracy of human brain is less than PLC.
