Advanced Handheld Communicator for Field Device Management
The Emerson AMS Trex Device Communicator is a portable field maintenance tool designed to simplify the configuration, commissioning and troubleshooting of intelligent process instruments.
Instead of carrying multiple specialized tools to the field, technicians can use the AMS Trex as an all-in-one device communicator for smart transmitters, control valves and other intelligent field devices. It provides direct access to device information, configuration parameters, diagnostics and process data, helping maintenance teams quickly identify and resolve instrument issues.
Typical applications include:
Pressure transmitter configuration
Flowmeter commissioning
Control valve diagnostics
Radar level instrument setup
Process loop troubleshooting
Field device maintenance
Supports HART and FOUNDATION Fieldbus Communication
The AMS Trex supports widely used industrial communication protocols, including:
HART®
FOUNDATION Fieldbus™
Bluetooth® device communication
This allows technicians to communicate with a broad range of intelligent field instruments from Emerson and other manufacturers.
The communicator includes a large device library supporting more than 2,500 field devices, enabling users to configure and troubleshoot instruments from multiple suppliers within a single platform.
Powerful Diagnostics for Faster Troubleshooting
Unexpected failures of field instruments can lead to production interruptions and increased maintenance costs.
The AMS Trex provides real-time access to device status, configuration information and diagnostic data, helping technicians identify problems directly at the installation site.
Key troubleshooting functions include:
Device status checking
Configuration verification
Loop diagnostics
Instrument parameter adjustment
Control valve testing
Fieldbus diagnostics
By reducing the need for physical inspection or device removal, the AMS Trex helps improve maintenance efficiency and reduce downtime.
Power the Loop Functionality
A key feature of the AMS Trex is its Power the Loop capability.
This function allows technicians to power compatible field devices directly from the communicator during commissioning or troubleshooting, reducing the need to carry additional power supplies or loop simulators.
Benefits include:
Faster device commissioning
Simplified bench testing
Easier troubleshooting before system power is available
Reduced maintenance equipment requirements
This makes the AMS Trex especially useful during plant installation, startup and maintenance activities.
Rugged and Intrinsically Safe Design
The AMS Trex is built specifically for industrial field environments where equipment must withstand harsh operating conditions.
The rugged housing provides resistance against:
Mechanical shock
Moisture exposure
Temperature variations
Industrial field conditions
With intrinsic safety certifications, the communicator can be used in hazardous areas when configured according to applicable requirements, making it suitable for industries with strict safety standards.
Bluetooth Connectivity and Modern User Experience
The latest AMS Trex platform introduces improved processing performance and embedded Bluetooth connectivity, enabling easier wireless interaction with compatible devices.
The modern interface provides:
Faster operation
Improved navigation
Application-based workflows
Easier access to maintenance functions
Bluetooth connectivity also expands integration possibilities with compatible field devices and applications, helping technicians work more efficiently in the field.
Integrated Applications for Different Maintenance Tasks
The AMS Trex uses an application-based framework to support different field activities.
Available applications include:
Field Communicator
Device configuration tools
ValveLink Mobile
WirelessHART™ provisioning
Loop diagnostics
Fieldbus diagnostics
These task-focused applications help technicians perform commissioning, configuration and troubleshooting using a single handheld platform.
Automatic Data Synchronization and Asset Management
The AMS Trex can synchronize field configuration changes with AMS Device Manager, helping maintain accurate device records and improve asset management.
This provides benefits such as:
Improved configuration tracking
Better audit documentation
Reduced manual data entry
More accurate maintenance records
For large industrial facilities with thousands of instruments, this helps improve overall device lifecycle management.
