The HART TREX Communicator expands the long line of Emerson handheld devices while adding new capabilities that adapt it to consumer expectations for mobile device functionality.

Technicians working with a Trex Communicator won't waste time bringing device back to the shop for analysis or configuration, problems with Foundation Fieldbus and HART devices can be diagnosed in the field while the devices are still installed. Simple issues can be addressed on the spot, avoiding unnecessary, and potentially destructive, invasive physical investigation of the problem.

Technicians require powerful and portable diagnostic tools so that they can identify and troubleshoot device issues to minimise process upsets. With a Trex Communicator in hand, users can properly diagnose device issues in the field. With the right handheld device, maintenance teams will experience significant savings in work hours and peace of mind knowing that problems will be fixed quickly and properly first time.

Once changes are made in the field, AMS Trex will automatically synchronise the information with the AMS Device Manager database via WiFi or USB connection.
