In the context of strong digital transformation in the era of Industry 4.0, establishing an internal network system is no longer an option – it’s a necessity for manufacturing enterprises. A stable, secure, and efficient LAN network serves as the foundation for connecting production data, optimizing operations, and enhancing process control across the entire factory. So, where should businesses start to build an internal network suitable for modern production models?

1. Why do manufacturing companies need a strong internal network system?

Unlike conventional enterprises, the factory environment is characterized by many parallel operating devices, real-time data, and extremely low latency requirements. A well-designed industrial network infrastructure can help:

  • Ensure continuous connectivity between departments and factory sites.
  • Integrate monitoring systems, CNC machinery, and IoT sensors.
  • Optimize production processes and inventory management.
  • Enhance data security and stability of production data.

2. Steps to deploy the factory LAN

Step 1: Assess the needs and scale of operations

First, businesses need to determine:

  • Factory size and number of devices to be connected.
  • Number of concurrent users accessing the network.
  • Production management systems (MES, ERP, SCADA) need to be integrated.
  • A detailed assessment helps define the required bandwidth and select the appropriate network technology.

Step 2: Choose industrial network equipment

Due to high interference and dusty environments, businesses should prioritize:

  • Industrial switches (metal casing, heat-resistant, dustproof).
  • Routers with VLAN, QoS, and firewall support.
  • Cat6 or Cat6A cabling for high-speed, durable connections.

If there is a need for long-distance data transmission or a high electromagnetic interference environment, the fiber optic system is the preferred choice.

Step 3: Design the optimal network model

An effective network model for the factory should follow the principles:

  • Network partitioning: clearly dividing networks for offices, machinery, surveillance cameras, IoT devices,…
  • Hierarchical structure: with core – distribution – access layers, ensuring easy management and expansion.
  • Connection redundancy: always have backup lines and devices to ensure uninterrupted operation.

Step 4: Ensure data safety and network security

Modern production systems are often targeted by cyber threats. Businesses should:

  • Deploy industrial firewalls, internal access authentication, and data encryption.
  • Set up user management policies, clearly assign rights to each access group.
  • Regularly update firmware and conduct network security audits to detect and prevent threats early.

Step 5: Plan for regular maintenance and expansion

Internal network infrastructure needs to be checked and maintained periodically to avoid interruptions:

  • Schedule regular equipment checks (every 3 – 6 months).
  • Have an expansion plan for the next 3 – 5 years, especially when expanding the production line.
  • Use network monitoring software to monitor equipment status 24/7.
