What Is A Device Type Manager (dtm)?

1.	What Is A Device Type Manager (dtm)?
Answer» A Device Type Manager (DTM) is part of the FDT standard that is a software COMPONENT for a device that contains the device-specific data, functions and logic elements. DTMs can reach from a simple graphical user interface for SETTING device parameters up to a highly sophisticated application that, for example, can perform complex CALCULATIONS for diagnostics and maintenance purposes or can implement arbitrarily complex business logics for device calibration. The DTM also contains FDT-compliant interfaces to enable communication with the connected system or tool. DTMs are classified as Device DTMs, which represent a field device, and CommDTMs, which represent communication components (GATEWAYS, remote I/Os, couplers, etc.). A typical FDT based application can contain dozens, hundreds, or thousands of Device DTMs and CommDTMs from a variety of manufacturers to make up the system.
