The DTM provides not only the configuration, manipulation and monitoring
functions for a device including the user interface functions, it also provides
the connection technology to the device.
In general, a DTM is a Microsoft COM-component, which can be executed
from within a FDT container application. A DTM is not a stand-alone tool, it
requires a FDT container application to be executed. The DTM provides a
number of interface functions, through which it can be controlled and
accessed in order to transfer data to or from the DTM.
A DTM provides all the options for configuration and monitoring of a device,
which it can present to the user through its own user interface.
The user interface for a DTM is provided using ActiveX windows. Control of
these windows is done by the DTM, but the FDT container application can
request specific user input from the DTM, based on which the DTM will pro-
vide the necessary ActiveX windows. In general multi-language user interface
windows, including DTM specific Help files are supported by the DTM.
Data transfer to and from a DTM is provided using XML-documents. The
XML-documents are standardized for the communication between the FDT
container application and for communication between DTMs.
An additional specification covers the definition of XML-data formats for the
transfer of application specific data, such as PROFIBUS data.
In general, a device configuration DTM is accompanied by a communication
DTM. This specific DTM facilitates device specific communication, e.g. for
downloading a configuration to a PROFIBUS Master Unit and/or for retrieving
monitoring information from PROFIBUS Master Unit. It may incorporate the
specific communication protocol, or rely on other available drivers.
CX-Profibus is a FDT container application. Together with this container appli-
cation, OMRON provides four DTMs:
• A DTM to facilitate configuration and operation of the CS1/CJ1W-PRM21
PROFIBUS DP-V1 Master Units (As of Unit version 2.0)
• A DTM to facilitate configuration of the CS1/CJ1W-PRM21 PROFIBUS
DP Master Units (Unit version 1.0)
• A DTM to facilitate configuration of the C200HW-PRM21 PROFIBUS
Master Unit
• A DTM to facilitate integration of GSD file based devices into CX-Profibus
(see section 1-2-3 GSD file Technology for more information)
The older and most commonly used configuration technology is the based on
GSD files (General Slave Data file). A GSD file is a text file, containing the
characteristic features and configuration options of a device. The device data
base file of each device is loaded in the configurator and downloaded to the
master device.
GSD files are usually supplied with a Unit, or can be downloaded from the
Internet, either from the manufacturer's site, or from the GSD library of the
PROFIBUS International at http://www.profibus.com.
