The handheld AMS Trex Device Communicator (photo) is built to withstand harsh industrial environments, and makes device and loop diagnostics simple to understand and field activities easier to complete. Protected against moisture and extreme temperatures, the Trex communicator boasts a rugged design that can withstand the bumps and drops that come from normal use in the plant. The large, full-color touchscreen display adjusts to lighting conditions and aids troubleshooting in areas where too much or too little light makes other devices difficult to read. Using the Trex communicator’s built-in Foundation Fieldbus and HART device diagnostic software, technicians can isolate and repair problems while the devices continue to run. Simple issues can be addressed on the spot, avoiding unnecessary production interruptions. Segment and loop diagnostic tools allow users to validate loop and fieldbus segment characteristics for streamlined troubleshooting. With the ValveLink Mobile app, technicians can analyze valve diagnostics results easily on the communicator’s larger screen. — Emerson Automation Solutions, St. Louis, Mo.
