Network Visualization

The network visualization provides an interactive diagram of your Sparkplug B topology. It shows every group, edge node, and device in your space as a connected graph.

How It Works

AnywhereSCADA builds the network diagram automatically from Sparkplug B birth and death certificates:

  • NBIRTH — a new edge node appears on the diagram
  • DBIRTH — a device appears connected to its parent node
  • NDEATH / DDEATH — the node or device is marked offline

No manual configuration is required. The diagram updates in real time as devices connect and disconnect.

Reading the Diagram

The diagram uses a hierarchical layout:

  • Groups — top-level containers, shown as the outermost nodes
  • Edge Nodes — gateways or applications, connected to their group
  • Devices — individual equipment, connected to their parent edge node

Status Indicators

  • Green — online and actively publishing data
  • Gray / faded — offline (death certificate received or connection lost)

Interacting with the Diagram

  • Pan — click and drag the background to move around
  • Zoom — scroll to zoom in and out
  • Select — click a node or device to highlight it and see its details

Use Cases

  • Commissioning — verify that all expected devices appear and show as online
  • Troubleshooting — quickly identify which nodes or devices have dropped offline
  • Overview — get a visual summary of your entire Sparkplug B network at a glance

Tips

  • Devices that frequently disconnect and reconnect may indicate network instability or misconfigured keep-alive intervals
  • The diagram reflects the Sparkplug B group/node/device hierarchy exactly as published by your edge nodes — if the structure looks wrong, check your Sparkplug B topic configuration
  • For large networks, use zoom and pan to navigate to specific areas
