Which utility shows the layout of every network configured in RSLinx?

The utility that displays the layout of every network configured in RSLinx is the Who Active tool. This tool provides a real-time view of all devices connected to a network and their status. It effectively shows you the devices that are currently active and communicating on the network, helping users to understand the network configuration and performance.

By capturing this information, Who Active allows users to troubleshoot network issues, verify device connections, and monitor communication in real-time, making it an essential tool for managing complex automation setups. This capability is particularly useful in environments where multiple devices are connected, as it provides immediate feedback on device health and activity.
