DtmCategory

Specifies the category of a DTM. The different DTM categories reflect the physical entities which are represented by a DTM. (Provides mapping to Fdt.Dtm.DtmCategory).
The fields of the DtmCategory DataType are defined in the following table:
Name | Value | Description |
---|---|---|
DeviceDTM | 0 | A Device DTM contains the application software for a ‘normal’ field device, e.g. a pressure transmitter or, a valve or a drive. |
CommunicationDTM | 1 | A Communication DTM is a special category of DTM containing the application software for specific communication hardware. |
GatewayDTM | 2 | A Gateway DTM is a special category of DTM representing a device that connects different fieldbus segments. |
CompositeDeviceDTM | 3 | A Composite DTM is a special category of DTM which is similar to a gateway DTM. A Composite DTM is the parent of a Module DTM and is intended to represent a header station of a modular device. |
ModuleDTM | 4 | A Module DTM is a special kind of DTM which is similar to a device DTM. A Module DTM is a child of a Composite DTM and is intended to represent a single module of a modular device. |
BlockTypeManager | 5 | A Block Type Manager (BTM) is a special category of DTM containing the application software for accessible objects inside a device such as function blocks and resource blocks. It is a child of a Device DTM. |
