To configure a new IP address for a controller connected to an Ethernet/IP network, which software is used?

The correct software used to configure a new IP address for a controller connected to an Ethernet/IP network is RSLinx. RSLinx is a communication server that provides tools for connecting to and managing Rockwell Automation devices on a network. It serves as a bridge for programming, monitoring, and configuring devices within the Rockwell environment, which includes setting up the IP addresses and communication parameters for various controllers.

When modifying network settings such as IP addresses, it's essential to use RSLinx as it facilitates easy access and configuration of devices on the Ethernet/IP network and ensures that communication between the device and the programming software is managed correctly. By leveraging RSLinx, engineers and technicians can maintain effective communication and reduce the risk of configuration errors, thus streamlining the setup process for controllers on a network.

Other software options may not have the same direct functionality for IP address configuration on an Ethernet/IP network. Logix Designer primarily focuses on creating and managing control logic and projects rather than network settings directly. While other Rockwell Automation tools may provide some networking features, RSLinx is specifically designed for communication management and IP configuration, making it the best choice in this scenario.
