ABB has incorporated power supply through Ethernet connectivity on board the latest edition of their electromagnetic flowmeter ProcessMaster and mass flowmeter CoriolisMaster, opening a new chapter in instrumentation and industrial communication. Ethernet connectivity for the ProcessMaster is currently available in North America only, it will be released globally later in 2021.
Power over Ethernet (PoE) offers several benefits for process engineers, as it omits the need for a separate DC power infrastructure, providing power and communications via the same cable. This brings new agility as flowmeters can be installed wherever needed. In addition, ABB 4-wire Ethernet combines classic outputs with future communication protocols. Offering a modular design allows the combination of both worlds and ensures that devices are future-proof, increasing the longevity of the flowmeters. Furthermore, flowmeters with Ethernet connectivity increase simplicity, flexibility and reliability to operations in process automation, while enhancing real-time visibility of data. Previously hidden data in field devices, such as measurement values on density, conductivity or concentration of the medium, can be unlocked. This in turn will help customers across all industries identify redundant measurement points in their plants to achieve savings along the way.
An integrated secure webserver based on the ABB Ability™ Cyber Security framework ensures robust and secure operations that offer instrumentation engineers support during commissioning and troubleshooting. It also provides access to configuration, diagnostics and measurement data through a built-in QR code. This allows verification of all parts of the flowmeter and provides insights into its operating condition with automatically generated reports. Combining 4…20 mA or digital outputs with new 1- or 2-port Ethernet makes classic instrumentation truly future-proof, with speeds of up to 100Mbit/s. The flowmeters use various Ethernet based communication protocols, such as simple Modbus TCP or high performance EtherNet/IP. This prepares them for IT/OT convergence, cloud connectivity and the requirements needed for secure and encrypted communication both today and tomorrow.
