Communication Integration|Site deployment
Communication integration and deployment for large BESS sites — topology, VLAN, redundancy, diagnostics and cable engineering.
What site network engineering must deliver beyond a protocol catalog Demo data
Who owns each class — and how five layers connect on site Demo data
| Class | Qty | Protocol | Ports | Owner | Criticality |
|---|---|---|---|---|---|
| BMS / BMU | 32 | CAN / TCP | 2×CAN · 2×FE | Battery OEM | Critical |
| PCS | 16 | Modbus TCP | ETH1/2 | PCS vendor | Critical |
| EMS / SCADA | 2 | IEC 61850 demo | FE · FO | System | Critical |
| Meter / gate | 8 | Modbus TCP | FE | EPC | High |
| HVAC / fire | 6 | Modbus RTU | RS485 | MEP | High |
| O&M jump | 2 | HTTPS | DMZ | Owner IT | Medium |
Semantic mapping
Adapters normalize units, precision, quality timestamps, buffer rates and fault mapping — ambiguous maps are rejected Demo data
Z1–Z5 plus OOB template — no flat LAN, no duplicate IDs Demo data · site TCN26

|---|---|---|---|---|
| Z1 Device | 10 | 10.10.10.0/24 | 10.10.10.1 | Field devices |
| Z2 Control | 20 | 10.10.20.0/24 | 10.10.20.1 | Control switches |
| Z3 Station | 30 | 10.10.30.0/24 | 10.10.30.1 | Core / PTP |
| Z4 DMZ | 40 | 10.10.40.0/24 | 10.10.40.1 | O&M / hist |
