4-4 Generic IO Device DTM
There are two means to represent a PROFINET IO Device for configuration in
CX-ConfiguratorFDT.
1 The GSDML file basically describes a IO Device by showing the selectable
modules an IO device can contain and its settable parameters. However,
online configuration is not possible with a GSDML file.
A GSDML file is mandatory for every PROFINET IO Device, in order to
enable any IO Controller to be configured for communication with the IO
Device.
A PROFINET GSDML file is comparable to a PROFIBUS GSD file.
However, a PROFINET GSDML file is in XML format while a PROFIBUS
GSD file is in plain ASCII text format.
2 A DTM (Device Type Manager) is a program that runs in a FDT (Field
Device Tool) container. It fulfils the basic function of a GSDML file by
supplying the module and parameter information to the IO Controller. In
addition it can also go directly online with the actual IO Device and allow
online configuration. To accommodate the user, normally a DTM has
intuitive screens to help the user configuring the IO Device.
The module and parameter information is passed to the IO Controller DTM so
it can be used to build a configuration file. When this file is downloaded into
the IO Controller it can perform I/O Data-exchange with the IO Devices.
4-4-1 Installing GSDML file
Install Device Description
File The Device Catalogue window contains a Install Device Description File
button. Clicking the button opens a file selection box from where different
types of files can be imported. For the moment only GSD-files for PROFIBUS
devices and GSDML files for PROFINET IO Devices can be selected.
The GSDML files are stored in a separate sub-directory under CX-
ConfiguratorFDT. Upon updating the Device Catalogue, the Generic IO Device
DTM will scan this sub-directory and present an entry in the Device Catalogue
for each of the GSDML files found.
Upon adding the GSDML based IO Device to the network, an instance of the
Generic IO Device DTM is created in PC memory, used for reading the
GSDML file contents and for providing the user interface necessary to make
the settings for the associated slave device.
4-4-2 Configuration User Interface
Opening the Configuration
DTM To open the configuration DTM:
• Select and double-click the IO Device DTM entry in the Network view or,
• Right-click the IO Device DTM in the Network view, and select
Configuration from the context menu.
The IO Device DTM Configuration User Interface, which is displayed in the
CX-ConfiguratorFDT DTM view is shown below. The figure shows the user
interface for an PROFINET IO Device Unit. By default the Configuration tab is
opened.
