20 Fluid Components International LLC
ST100 HART DTM
The ST100 product of family supports FDT-DTM Functionality through the HART Protocol 7.3. Fluid Components International
provides DTM files for the ST100 HART device. This chapter describes the following:
• What is FDT-DTM Technology
• How it works with ST100 HART device
• Examples/Screenshots for ST100 HART DTM
What is FDT-DTM Technology?
Field devices have gained intelligence along with the spread of digital communication. As the number of intelligent devices
increases, the more complicated settings and adjustments needed to use the advance functions in such devices. FDT (Field De-
vice Tool) is a software architecture that lets field devices be set and adjusted in an open framework independent of a specific
host system. FDT standardizes the communication and configuration interface between all field devices and host systems. FDT
provides a common environment for accessing the device’s most sophisticated features.
DTM stands for Device Type Manager, which at its core is a device driver. There are two DTM categories.
1. Device DTMs which connect to the field device configuration components
2. Communication DTMs which connect to the software communication components.
The DTM provides a unified structure for accessing device parameters, configuring and operating the devices, and diagnosing
problems. DTMs can range from a simple Graphical User Interface for setting device parameters to a highly sophisticated ap-
plication capable of performing complex real-time calculations for diagnosis and maintenance purposes.
How it works with the ST100 HART device?
The relationship between the FDT frame application and DTM is similar to that between the Windows Office application and
Printer driver. A dedicated printer driver is provided for each printer and a standard interface is available in each printer driver.
The Office applications can print data on any printer via this standard interface. In FDT, a DTM driver specific to a field device is
provided and a standard interface is available in this driver. FDT frame applications such as the engineering system and asset
management system can use the field devices via the FDT interface.
