Alright, put on your curious hat and let’s learn together with Sister Fang!

1. PLC and DeepSeek in Industry 4.0: Perfect Partners

In the era of Industry 4.0, factories are becoming increasingly “smart”.

Here, “smart” refers to more automated and intelligent production.

Traditional PLC systems excel at logical control and real-time response, but they struggle with complex data analysis and prediction.

At this point, the addition of artificial intelligence technologies like DeepSeek is like equipping the factory with a “smart brain”.

In simple terms:

PLC is the “executor” on the production line, responsible for real-time control of mechanical equipment, such as starting, stopping, timing, and detection.
DeepSeek is the “analyst”, responsible for analyzing and optimizing massive amounts of data, such as predicting equipment failures and optimizing production rhythms.

The combination of the two is like a pair of perfectly coordinated partners, capable of steadily completing basic operations while dynamically adjusting strategies to make production more efficient.

2. Application Case: Intelligent Upgrade of Food Packaging Production Line

Next, Sister Fang will use a case of a food packaging production line to show you how PLC and DeepSeek collaborate.

1. Case Background

A certain food factory has a packaging production line that is always troubled by the following issues:

Unstable packaging rhythm, leading to low production efficiency.
Equipment occasionally experiences stalling or failures, but maintenance is always reactive, unable to prevent issues in advance.
Production data cannot be fully utilized, making it impossible to effectively optimize processes.

To solve these problems, the factory decided to integrate the DeepSeek intelligent analysis module based on the existing PLC control system (Siemens S7-1500). The goals are:

To achieve dynamic optimization of packaging rhythm.
To improve the stability and reliability of equipment operation.
To utilize data mining to optimize production processes.

2. Collaboration between PLC and DeepSeek

In this case, PLC and DeepSeek each play their roles to complete tasks together:

PLC is responsible for basic control① Control key devices on the production line, such as motors, sensors, packaging machines, etc.② Achieve real-time logical control, including starting, stopping, timing, etc.③ Collect real-time data from the production line, such as motor torque, packaging quantity, operating status, etc.
DeepSeek is responsible for intelligent analysis① Deeply analyze the data collected by PLC, such as equipment operating parameters, historical failure records, etc.② Predict potential failure risks of equipment and provide maintenance suggestions in advance.③ Optimize packaging rhythm through AI algorithms, dynamically adjust the operating parameters of servo motors, and reduce waiting time.

3. Implementation Ideas of the Case

(1) Hardware Configuration

The required hardware devices for this case include:

Siemens S7-1500 PLC: Used for the underlying control of the production line.
DeepSeek Industrial AI Edge Box: Used for data analysis and AI optimization.
Servo Motor: Achieves precise control of the packaging machine.
Sensor: Used for real-time detection of production status, such as completed packaging quantity, equipment status, etc.

(2) Design Process

Data CollectionPLC collects key data from the production line through the Profinet communication protocol, such as packaging quantity per minute, motor operating status, etc., and transmits the data to the DeepSeek box.
AI Analysis and OptimizationDeepSeek uses built-in algorithms to analyze historical and real-time data, identifying bottlenecks in production. For example, if it finds that a motor’s operating speed is too high, causing instability in packaging rhythm, it will provide optimization suggestions.
Optimization FeedbackDeepSeek sends the optimized parameters (such as motor acceleration, operating rhythm time, etc.) back to the PLC via the Modbus TCP protocol, and the PLC dynamically adjusts the production process based on the new parameters to achieve efficiency improvement.

4. Results and Benefits

Through this intelligent upgrade, the factory’s production efficiency increased by over 10%, and the equipment failure rate decreased by 20%. More importantly, the factory began to utilize data for decision-making, rather than solving problems reactively as before.

3. Debugging and Precautions

In actual implementation, debugging is a very important step. Sister Fang has compiled some common problems and solutions for you:

1. Communication Issues

Problem: Intermittent communication between PLC and DeepSeek box.
Solution: Check the Profinet or Modbus TCP communication configuration to ensure data block addresses are consistent.

2. Data Delay

Problem: There is a delay when DeepSeek sends optimized parameters back to PLC.
Solution: Try to complete real-time optimization through edge computing to reduce the steps of uploading data to the cloud.

3. Incorrect Parameter Settings

Problem: AI optimization parameters do not meet production needs, leading to abnormal rhythms.
Solution: During initial debugging, strictly check whether the input parameters of the optimization model are accurate and ensure data backup.

4. Application Expansion: More Scenarios of Possibility

In addition to food packaging, this “PLC + DeepSeek” intelligent solution can also be applied in the following scenarios:

Automobile Manufacturing: Optimize the action rhythm of robotic arms to improve assembly efficiency.
Chemical Production: Predict equipment failures to reduce safety risks.
Logistics Sorting: Dynamically adjust the operating strategies of sorting machines to enhance sorting speed.

As long as there is data and control needs, this solution can be applied to almost any industrial scenario.

5. Summary and Encouragement

Today, through a case of a food packaging production line, we learned about the combination of PLC and DeepSeek in Industry 4.0, and I hope you have gained a more intuitive understanding of this technology.
