Emerson was named a Top Implementer in ABI Research's Industrial Automation: PLC Hardware and Software competitive ranking. Emerson’s PLC solution has an open design, supporting connections to MODBUS, PROFIBUS, and DNP3, among others, alongside having hot swapping functionality in its high availability systems. The key connection that the solution does not natively support is Ethernet IP, requiring a Connex gateway to connect to this. The Rx3i CPE300 has three different Ethernet ports, with the option to add an additional eight, providing manufacturers with a wide range of connectivity options.
