Applications and Cases

Modern automated factory with robotic arms and networked equipment enabling Industry 4.0 connectivity

Key Takeaways

Optimize your production line with high-speed, secure connectivity for Industry 4.0. InHand managed switches provide the low-latency networking and traffic isolation required to keep automated systems synchronized and production moving.

Background

Modern smart manufacturing relies on high-speed Ethernet to link PLCs, industrial robots, and human-machine interfaces (HMIs). However, intricate automated systems demand ultra-low latency and absolute network stability. A single packet delay can halt an entire production line, meaning frustration and potential revenue loss. Manufacturers are expecting devices that deliver secure, low-latency, and reliable connectivity.

Customer Requirements

Ultra-Low Latency
Transmission
The network must ensure deterministic delivery of control commands between the master PLC and field-level I/O to maintain high-precision motion control.
Robust Cybersecurity &
Process Isolation
The ability to segment different production zones and secure ports against unauthorized access is vital for protecting sensitive industrial assets and intellectual property.
Noise & Vibration
Resistance
Networking equipment must be resistant to the heavy electromagnetic noise and mechanical vibrations common in large-scale manufacturing plants.

Solution

Automated assembly line with robotic arms connected to industrial IoT switches in a smart factory

InHand managed switches are integrated into the factory’s DIN-rail control panels to form a high-bandwidth communication backbone. Using RSTP/MSTP ring protection and advanced management protocols, the switches isolate critical automation traffic from general plant networks. This ensures that safety and control data is delivered with consistent, ultra-low latency, maintaining the perfect synchronization of automated production equipment.

Benefits

Maximized
Manufacturing Uptime
Support for RSTP/MSTP ring protection ensures automatic failover if a single cable is damaged, preventing production line stoppages and ensuring worker safety.
Hardened
Industrial Security
Features like port-binding and access control lists (ACLs) provide a strong first line of defense against network-based threats, ensuring only authorized devices can access the control network.
Flexible and
Scalable Expansion
The managed network architecture allows for the easy addition of new robots or sensors as the line evolves, with management tools ensuring the network remains stable as complexity increases.
