DESCRIPTION AND SPECIFICATIONS

OUNDATION
™ Fieldbus Communicators.
Both the Rosemount Model 375 (or 275) and a computer can be used to communicate with a HART transmitter. The 250 ohm load
(minimum) must be present between the transmitter and the power supply.
1.8 ASSET MANAGEMENT SOLUTIONS
Asset Management Solutions (AMS) is software that helps plant personnel better monitor the performance of analytical
instruments, pressure and temperature transmitters, and control valves. Continuous monitoring means maintenance per-
sonnel can anticipate equipment failures and plan preventative measures before costly breakdown maintenance is
required.
AMS uses remote monitoring. The operator, sitting at a computer, can view measurement data, change program settings,
read diagnostic and warning messages, and retrieve historical data from any HART-compatible device, including the Model
XMT-C transmitter. Although AMS allows access to the basic functions of any HART compatible device, Rosemount
Analytical has developed additional software for that allows access to all features of the Model Xmt-C transmitter.
AMS can play a central role in plant quality assurance and quality control. Using AMS Audit Trail, plant operators can track
calibration frequency and results as well as warnings and diagnostic messages. The information is available to Audit Trail
whether calibrations were done using the infrared remote transmitter, the Model 375 HART communicator, or AMS soft-
ware.
AMS operates in Windows 2000, NT, and XP operating systems. See Figure 1-5 for a sample screen. AMS communicates
through a HART-compatible modem with any HART transmitters, including those from other manufacturers. AMS is also
compatible with FOUNDATION Fieldbus, which allows future upgrades to Fieldbus instruments.
Rosemount Analytical AMS windows provide access to all transmitter measurement and configuration variables. The
user can read raw data, final data, and program settings and can reconfigure the transmitter from anywhere in the plant.
