Emerson introduces ‘industry’s first’ pneumatic valve system with embedded wireless connectivity18 September 2020
Emerson has launched a wireless automatic recovery module (ARM) for its Aventics G3 electronic fieldbus platform to help technicians to perform pneumatic valve system commissioning and diagnostics from a mobile phone, tablet or laptop computer.
“The Aventics G3 fieldbus platform is the first in the industry to offer wireless technology that puts valve system configuration and diagnostics at the control engineer´s fingertips,” said Enrico De Carolis, vice president of global technology, fluid control and pneumatics, at Emerson.
The new wireless ARM module and Aventics G3 fieldbus platform are said to be ideal for pneumatic valve system applications in the automotive, food and beverage, tire, packaging and metalworking industries. “A replacement G3 fieldbus communication node can automatically download the required parameters from the ARM module,” said De Carolis. “This enables the valve system and production line to quickly resume operation without the need for re-commissioning by a controls engineer.”
The module provides access to the Aventics G3 fieldbus platform´s diagnostic and commissioning capabilities via an internal Wi-Fi access point and mobile website — even when the valve system is located inside a machine or on a ceiling. The module generates error notification for alarms, voltage levels, short circuits, module errors, open load errors and distribution errors, to reduce system downtime.
The device connects to the Aventics G3 fieldbus platform in the space of a jumper clip. It features three power settings for low-, medium-, or high-distance signals to ensure safe and secure access to data. Additional security benefits include wireless signal that can be turned off during configuration, multiple password options, and diagnostic and commissioning information provided with no control capability.
The wireless ARM module is compatible with Ethernet/IP DLR, and PROFINET protocols. Additional protocols are targeted for future release.
Emerson also has introduced an upgraded ARM clip for the Aventics G3 fieldbus platform that is backwardly compatible to existing ARMs and G3 fieldbus platforms. The ARM clip improves system reliability by protecting configuration information from critical valve system failure. The Aventics G3 fieldbus platform´s electronic parameters and settings are automatically stored in the ARM´s nonvolatile memory and then the ARM is automatically disconnected from power, to ensure stored information is not erased during a power spike or critical failure.
