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, along with any connected MQTT clients.

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.

Viewing the Diagram

Toggle the Overview section on your space page to show or hide the network diagram. The diagram displays a real-time count of connected MQTT clients alongside the topology.

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
