Issue
Guidance is required for configuring a Sigma Distributed Network Node (DNN) when connecting it to a "Flat" Ethernet network.
Product Line
Satchwell BAS & Sigma
Environment
- Satchwell Sigma
- Ethernet network
- Ethernet or ARCnet subnets
Cause
General configuration advice for ensuring proper communication between Sigma controllers and the network via the DNN.
Resolution

What Is a Flat Ethernet Network?
A flat Ethernet network is a network architecture where all devices share the same broadcast domain and IP subnet.- There are no routers or subnets separating groups of devices.
- All devices can communicate directly without routing.
- Typically uses a single IP range and subnet mask, such as 10.158.0.0/16.
- Simplifies configuration but may lead to scalability and performance issues in larger environments.
-
Network Configuration
- On a flat Ethernet network, the DNN requires only:
- IP address
- Subnet mask
- These settings, along with the DNN’s “Default Server” information, should be configured using the Sigma Device Configuration Utility (SDCU).
- On a flat Ethernet network, the DNN requires only:
-
Routing Configuration
- RIP (Routing Information Protocol) is enabled by default on the DNN.
- If RIP is enabled, the DNN will broadcast the route to the sublan.
- If RIP is disabled, a persistent route must be manually added to the Sigma server.
- Refer to the article: Persistent routing on the Sigma server for detailed steps.
- RIP (Routing Information Protocol) is enabled by default on the DNN.
