Phoenix Contact updates Ethernet HART® Multiplexer: Now Compatible with Emerson’s AMS Device Manager

Middletown, Pa. – A firmware update is available for Phoenix Contact’s Ethernet HART multiplexer that adds support for the ARCOM protocol, enabling connectivity with Emerson‘s AMS Device Manager asset management software, which helps avoid unnecessary downtime by providing a window into the health of intelligent field devices. Emerson conducted and completed compatibility testing at its Eden Prairie, Minnesota facility.

The GW PL ETH/-... multiplexer provides a simple way to parameterize and monitor field devices on an Ethernet network, and is an up-to-date replacement for widely used RS-485 HART multiplexers. Designed for applications like partial-stroke testing, valve diagnostics, and batch-data transfers, the multiplexer features a HART master on each channel for the fastest possible updates and execution times. Integration into the market-leading AMS Device Manager software allows HART users to perform operations that save time and money.

The multiplexer consists of a head station and a variety of HART expansion modules to suit any application need. The modular design allows up to five expansion modules to be connected to a single head station. That makes this a scalable solution for modern, distributed control systems and phased roll-outs. In addition to the new ARCOM support, the multiplexer also supports HART IP, features a CommDTM for integration into an FDT Frame application, and converts HART parameters into Modbus TCP or Profinet.

The new firmware and DD files are available to download from or the Emerson device download site at:

All of the modules are rated for use in UL Class I, Division 2 and ATEX/IECEx Zone 2 hazardous locations and operate in -40 to 70 degree Celsius temperature extremes. Learn more at
