What are the common PLC programming software for PLC programming algorithms?

PLC programming is an electronic system of digital computing operations, designed for use in industrial environments. PLC programming has a wide range of applications, powerful functions, and is easy to use. It has become one of the main devices of contemporary industrial automation and has been widely used in all fields of industrial production. Its application in other fields (such as civil and home automation) has also been rapidly developed.

There are several algorithms for PLC programming:

1. Sequential control algorithm: Execute each logic function module in sequence according to the order specified by the program. It is the most basic PLC programming algorithm.

2. Simulation control algorithm: The value of each variable is calculated through the simulation model, and then controlled according to certain rules.

3. Event-driven algorithm: triggers the corresponding PLC program when a specific event occurs, such as sensor output signal, communication data arrival, etc.

4. State machine algorithm: Utilize the idea of ​​finite state machine to program operations under different states and realize the control of system state.

5. Orthogonal programming algorithm: Write the program separately according to the three parts of "input-processing-output" to improve the readability and maintainability of the program.

6. Strategy algorithm: Write programs according to different control strategies, such as PID control, fuzzy control, etc.

The above are the commonly used algorithms in PLC programming. Different PLC programming languages ​​and different PLC brands may have some slight differences.

Common PLC programming software include:

1. Siemens STEP 7: Siemens' own PLC programming software, mainly used for programming S7 series PLCs.

2. Rockwell Studio 5000: Rockwell's own PLC programming software, mainly used for programming ControlLogix series PLCs.

3. Mitsubishi GX Works: Mitsubishi's own PLC programming software, mainly used for programming FX, Q, and L series PLCs.

4. Omron CX-Programmer: Omron's own PLC programming software, mainly used for programming CP series PLCs.

5. Schneider Unity Pro: Schneider's own PLC programming software, mainly used for programming M340, Quantum and Premium series PLCs.

6. Beckhoff TwinCAT: PLC programming software from Beckhoff, mainly used for TwinCAT motion control and machine vision programming.

Etc. The above are just a few common PLC programming software, and there are other programming software for different PLC brands and models.

With the automation of modern industrial equipment, more and more factory equipment will be controlled by automation devices such as PLC human-machine interface, so the degree of equipment automation is getting higher and higher. The technical requirements for equipment maintenance personnel are becoming more and more stringent. As a qualified technician, you need to master more and more skills and become more comprehensive to meet the development and requirements of automation.
