Process-Area Managed Access and Traffic Isolation
Managed industrial switches VLAN-separate process monitoring, video, and maint terminals.
1. Scenario
One process area mixes DCS/PLC monitoring, patrol video, and maint laptops—needs controlled access.
2. Challenges
Broadcast chaos; rogue endpoints; ring/redundancy needs.
3. Architecture
Cabinet 8GE+2/4SFP managed; port security+VLAN; fiber ring or uplink to control room.
4. Recommended Leagrid LGS2000 products
- LGS2000-8GE2GF-M: Managed Gigabit industrial switch: 8×GE copper + 2×GE SFP; VLAN/QoS/ring redundancy for intersection and shop-floor aggregation.
- LGS2000-8GE4GF-M: Managed Gigabit switch: 8×GE copper + 4×GE SFP for multi-direction fiber rings and multi-camera uplinks.
5. Deployment notes
Rate-limit/time-box maint VLAN; never bridge office laptops into process VLAN; dual review for changes.
