What is the purpose of the RSWho screen in the PLC environment?

The RSWho screen serves a crucial role in the PLC environment by providing an interface for users to view and set communication paths between various devices on a network. This feature allows users to identify which devices are connected to the PLC and how they communicate with one another. By using the RSWho screen, users can manage connections and ensure that communication pathways are correctly established for optimal operation of the automation system.

This functionality is vital because improper communication settings can lead to failures in data transmission between devices, disrupting the entire control system. The RSWho screen simplifies the management of these connections, making it easier to troubleshoot issues related to communication as they arise.
