CJ1W-PNT21 configuration
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:
•
•
The DTM is an executable component provided by the device vendor to be
used in an FDT Container program like OMRON's CX-ConfiguratorFDT (see
also Appendix A PROFINET IO technology, FDT/DTM Technology). 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 information 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:
•
•
•
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 information 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 configuring the PROFINET IO Controller. The GSDML file
does not provide the means to access data of the IO Device Units directly.
To configure the I/O Data exchange between the IO Controller an the IO
Devices, the user must use the Configuration User Interface to define the
configuration of PROFINET IO Devices connected 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:
•
•
•
The Monitoring User Interface allows the user to read information from the
PROFINET IO Controller. The Interface also provides a means to read the
Error Log of the
connected PROFINET IO Devices.
After setting up the configuration, it must be downloaded to the PROFINET IO
Controller Unit.

PROFINET I/O Configuration
Configuration of the individual parameters of an IO Device
Monitoring of an I/O Device
It is used by the PROFINET IO Controller Unit when mapping the I/O data
of individual PROFINET IO Devices onto the PLC 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 communication. 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 I/O 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 behaviour.
