What it actually is

This is NOT a PLC or control module.

It is a network infrastructure device, meaning:

• Connects PLCs, HMIs, drives, and I/O systems together
• Distributes PROFINET / Ethernet communication
• Improves network reliability in industrial environments

It does NOT:

• Execute automation logic ❌
• Control machines directly ❌
• Process signals ❌

System Role (Simple)

PLC / HMI / Drive / ET200
→ Ethernet cables
→ SCALANCE X116 switch (this device)
→ distributed communication network
→ all devices communicate together

So it acts like a “traffic hub for industrial Ethernet communication”.

Key Features

• 16-port industrial Fast Ethernet switch
• Designed for harsh factory environments
• Supports PROFINET communication networks
• LED diagnostics for port status
• Fault signaling contact for maintenance systems
• Redundant power supply support (in many variants)
• Plug-and-play unmanaged operation (no configuration needed)

Typical Applications

• Factory automation networks
• PLC + HMI + drive communication networks
• PROFINET distributed I/O systems
• Industrial machine networking
• Production line Ethernet infrastructure

Advantages

• Very stable industrial-grade networking
• No configuration required (unmanaged type)
• Supports real-time PROFINET traffic
• Strong EMC resistance (factory environment)
• Easy expansion of PLC system ports

Important Notes

• Not a PLC ❌
• Not a communication module (like CP343/CP443) ❌
• Not an I/O module ❌
• It is a network switch (industrial Ethernet infrastructure device) ✔

Precautions

• Must use 24V industrial power supply
• Proper grounding required for EMI protection
• Do not confuse with managed SCALANCE switches (X200/X300 series)
• Cabling quality affects PROFINET stability
• Must be installed in control cabinet environment
