Function Data communication & integration

Programmable Logic Controller (PLC) is a digital electronic device with a microprocessor used for automation control. It can load control instructions into memory for storage and operation at any time. A programmable controller is composed of an internal CPU, instruction and data storage, input/output units, power modules, digital analog units, and other modular components. PLC can receive (input) and send (output) various types of electrical or electronic signals, and use them to control or supervise almost all types of mechanical and electrical systems.

At present, PLC controllers have been widely used in various industries such as steel, petroleum, chemical, power, building materials, machinery manufacturing, textiles, transportation, and cultural entertainment both domestically and internationally. The application of PLC can be roughly summarized into the following categories:

1. Switching control

The ability of PLC to control switch values is very strong. The number of input and output points controlled is almost unlimited, and the logical problems controlled can be diverse: combinatorial, sequential, immediate, delayed, uncountable, countable, fixed order, random operation, etc. It can be said that any existing problem can be solved. Moreover, due to its variable hardware structure and programmable software programs, it is very flexible when used for control. So, it can adapt to the changing situations in the workplace and can be converted at any time, which is why it is highly favored by the industrial industry.

2. In industrial production processes, there are many continuously changing quantities, such as temperature, pressure, flow rate, liquid level, and speed, which are all analog quantities. In order for a programmable controller to process analog signals, it is necessary to implement A/D conversion and D/A conversion between analog and digital signals. PLC manufacturers produce matching A/D and D/A conversion modules to enable programmable controllers for analog control. At present, not only large and medium-sized computers can perform analog control, but also small computers can perform such control.

3. Motion control

The actual physical quantities, in addition to switch values and analog values, also include motion control. The displacement of machine tool components is often represented by numerical quantities. The most effective method of motion control is NC. This is a computer-based control technology that was born in the 1950s in the United States and is now very popular. In terms of control mechanism configuration, in the early days, it was directly used to connect position sensors and actuators to switch I/O modules, but now specialized motion control modules are generally used. A single axis or multi axis position control module that can drive stepper motors or servo motors. Almost all major PLC controller manufacturers in the world have motion control functions in their products, which are widely used in various machinery, machine tools, robots, elevators, and other occasions.

4. Process control

Process control refers to closed-loop control of analog quantities such as temperature, pressure, and flow rate. As an industrial control computer, PLC can develop various control algorithm programs to achieve closed-loop control. PID regulation is a commonly used adjustment method in general closed-loop control systems. Large and medium-sized PLCs all have PID modules, and currently many small PLCs also have this functional module. PID processing generally involves running specialized PID subroutines. Process control has a wide range of applications in metallurgy, chemical engineering, heat treatment, boiler control, and other fields.

5. Data collection

With the development of PLC technology, its data storage area is also getting larger and larger. A huge data storage area that can store a large amount of data. Data collection can use a counter to accumulate and record the number of pulses collected, and periodically transfer them to the DM area. Data acquisition can also be done using an A/D unit, which converts analog signals into digital signals and then periodically stores them in the DM area. These data can be compared with reference values stored in memory to perform certain control operations, and can also be transmitted to other intelligent devices through communication functions or printed into tables.

PLC controller communication includes communication between PLC controllers and communication between PLC controllers and other intelligent devices. With the development of computer control, factory automation networks have developed rapidly, and PLCs can also be connected to personal computers for communication. Computers can participate in programming and control management of PLCs, making them more convenient to use. In order to fully utilize the role of computers, one computer can control and manage multiple PLCs, up to 32 of which can be used.

The Future Development Trend of PLC

No matter how it develops in the future, the excellent side of things will not be hidden, and PLC is no exception. No matter how it develops in the future, the stable control response and high reliability of PLC will inevitably be passed down. Therefore, it can be foreseen that its future development will be towards high speed and large capacity.

To improve the processing capability of PLC, it is required that PLC has better response speed and larger storage capacity. At present, the scanning speed of some PLCs can reach around 0.1ms/k steps. In terms of storage capacity, some PLCs can reach up to tens of megabytes. To expand storage capacity, some companies have used magnetic bubble memory or hard drives.

2. Develop towards two extreme directions of body shape.

There are currently many small and medium-sized PLCs, and in order to meet the various needs of the market, PLCs need to develop towards multiple varieties in the future, especially towards the two directions of ultra large and ultra small. There are now super large PLCs with 14336 I/O points, using 32-bit microprocessors, multiple CPUs working in parallel, and large capacity memory. The minimum configuration of O/O points is 8~16 points to meet the needs of single machine and small automatic control.

3. PLC vigorously develops intelligent modules and strengthens its networking and communication capabilities.

PLC manufacturers continue to develop many functional modules, such as the high-speed counting module, temperature control module, remote 1/O module, communication and human-machine interface module of Aoyue Xin. These intelligent I/O modules with CPU and memory not only expand the functions of PLC, but also are flexible and convenient to use, expanding the application scope of PLC.

4. Enhance the ability to detect and handle external faults.

According to statistical data, in PLC control system failures, CPU accounts for 5%, I/O interfaces account for 15%, input devices account for 45%, output devices account for 30%, and circuits account for 5%. 20% of the faults in the first two items are internal faults of the PLC; The remaining 80% of the faults are external faults of the PLC. Therefore, PLC manufacturers are committed to researching and developing specialized intelligent modules for detecting external faults, in order to further improve the reliability of the system.

The fifth is the diversification of programming languages.

As the structure of PLC systems continues to develop, the programming languages of PLCs are becoming increasingly rich and their functions are constantly improving. In addition to the ladder diagram language used by most PLCs, there have been gradually emerging programming languages for sequential control, flowchart languages for process control, and high-level languages compatible with computers. The coexistence, complementarity, and development of multiple programming languages are a trend in the progress of PLC.
