Overview of the characteristics of the integrated PROFINET IO device
In the network, the IDENTControl IC-KP-B17-AIDA1 is a PROFINET IO device that
communicates cyclically with the assigned PROFINET IO controller during operation. The
IDENTControl IC-KP-B17-AIDA1 supports the range of functions as per
Conformance Class B

Project planning using device description (GSDML)
As with PROFIBUS DP, the PROFINET IO device is integrated in the configuration tool by way
of a device description. The characteristics of an IO device are described in a GSDML (General
Station Description Markup Language), which contains all the relevant data related to a field
device (technical properties and information for communication) that is required to address and
operate the device in a PROFINET network. PROFINET uses the XML-based language
GSDML (General Station Description Markup Language) to describe the device.
The description files for the IO devices are imported into the configuration tool. Peripheral
addresses are assigned to the individual IO channels of the field devices. The peripheral input
addresses incorporate the received data. The user program evaluates and processes this data.
The user program generates the peripheral output values and sends them to the
IDENTControl.
Once programming is complete, the programming and configuration data is uploaded to the IO
controller. The IO controller programs and configures the IO devices automatically.
The following data field sizes (modules) are predefined in the GSD file:
For read/write operation:
For read only operation:
Select one of the predefined modules. In doing so, make sure that the data field size for the
read/write commands used is sufficient, depending on the parameter word count.

Note!
The data hold time is stored in the GSDML file. This value can be changed via the properties of
the PROFINET device.
