1-4 Basic Operating Procedures
The PROFINET IO Controller Unit must be configured before it can exchange I/O data with any of its IO
Devices. To configure the unit, information about the IO Devices must be available. OMRON provides
two means to provide an IO Controller Unit with IO Device information:
• by DTM
• by GSDML file
 Configuration by DTM
The DTM is an executable component provided by the device vendor to be used in an FDT Con-
tainer program like OMRON's CX-ConfiguratorFDT. The DTM runs inside this FDT Container and
has its own User Interface. It can access online parameters of the IO Device and present that infor-
mation to the user. It can also load and save the settings, using the features of the FDT Container
program. A DTM generally provides the user with the following features:
• PROFINET IO Configuration
• Configuration of the individual parameters of an IO Device
• Monitoring of an IO Device
 Configuration by GSDML File
The GSDML file concept is another way of configuration. The GSDML file is an XML-based file,
which contains all options required to configure a PROFINET IO Controller Unit. The file can be
loaded by the configuration software of the IO Controller Units, which will then present the informa-
tion to the user to allow the appropriate selections to be made.
The drawback of the GSDML file is that, unlike the DTM, it only provides setting options for configur-
ing the PROFINET IO Controller. The GSDML file does not provide the means to access data of the
IO Device Units directly.
 CJ1W-PNT21 IO Data Exchange Configuration
To configure the I/O Data exchange between the IO Controller and the IO Devices, the user must
use the Configuration User Interface to define the configuration of PROFINET IO Devices con-
nected to the PROFINET IO Controller Unit. It also allows the user to make parameter settings for
individual PROFINET IO Devices.
The I/O Data Exchange Configuration consists of the following parts:
• It is used by the PROFINET IO Controller Unit when mapping the I/O data of individual PRO-
FINET IO Devices onto the CPU memory areas.
• The I/O Data Exchange Configuration holds information that is sent by the PROFINET IO
Controller Unit to the PROFINET IO Devices for verification when establishing communica-
tion. The I/O configuration sent by the PROFINET IO Controller Unit must match the physical
configuration of PROFINET IO Devices to be able to proceed with IO data exchange
• Further parameters are sent from the IO Controller to the IO Device to setup the IO Device
properly. Parameters are used to setup for instance ranges, alarm limits and other runtime
behavior.
