With the rapid development of the domestic manufacturing industry, more and more manufacturers are transforming their operations into digital factories. Factories are filled with numerous devices and complex processes, and frontline workers are increasingly focused on handling and adjusting equipment. However, in digital factories, data collection and in-depth application remain one of the key challenges.

For tightening equipment on production lines, common related data collection includes: the tightening device itself, the operator, the result status, and related materials. The most common data collection methods are as follows: Industrial Ethernet, Fieldbus, I/O, and Serial Port.

Industrial Ethernet

When using Ethernet as the data collection channel, there are two common methods:

1. Using a Professional Data Collection System

Taking Danikor tools as an example, manufacturers can use Danikor’s dedicated collection and analysis software to gather relevant production line data. By utilizing the factory’s Ethernet network, tightening results, personnel information, and related data are collected into a database for storage and analysis. Most professional industrial tool manufacturers provide such data collection software.

2. Using Communication Protocols

Communication protocols differ from dedicated data software. Protocols support two-way communication: they can both control the tool and collect tightening results and other related information to the server. Server-based software can collect, display, and analyze data, while also enabling task execution, tool reset, and detailed logging of alarm statuses.

Fieldbus

Fieldbus is another common communication method. When PLCs are present on the production line, fieldbus modules are typically used for communication and centralized control of field devices.

I/O and Serial Port

Compared to professional data collection software, protocols, and fieldbus systems, I/O and serial port-based data collection is significantly more limited. As a result, these methods are rarely used in practice.

• I/O: Although it supports two-way communication, it only transmits on/off signals. This means it cannot collect specific torque values for critical bolt tightening operations, making it less useful.

• Serial Port: While it can transmit specific values, the process is unstable and poses a risk of data loss, so it is also rarely used on-site.

Conclusion

Factory data collection is not just for storage—it is more importantly used for data analysis and trend prediction. Only by maximizing the value of data can we align with the broader trend of data-driven industrial manufacturing.
