10 PROFINET IO interface
The device supports Ethernet networks with a transmission speed of 100 Mbit/s and
PROFINET RT, Conformance Class B in accordance with V2.2.
The Auto negotiation, auto crossover and full duplex functions are also implemented.
The device features an integrated dual port switch and can be used in a star or line
topology. The following functions, among others, are supported by the device: Media
Redundancy (MRP), Topology Detection (LLDP), Device Replacement without exchange‐
able medium/PG function and MIB/SNMP.
I&M functions (identification & maintenance functions)
The following I&M functions are supported:
•
I&M0: Device identification
•
I&M1: Users can enter system and location identification (AKZ and OKZ)
•
I&M2: Installation date
•
I&M3: Description of the function
•
I&M4: Signature (config CRC)
•
I&M5: Interface identification
The software revision of the IMO I&M function describes the version of the PROFINET
interface and is not identical to the version number of the sensor firmware.
10.1 Device project planning
The device is integrated into the control project with the help of the controller-specific
project planning tool (e.g., SIEMENS TIA Portal) using the generic station description
file (GSD). Project planning includes configuring the device (e.g., selecting the device
hardware and GSD modules for process and parameter data) as well as parameteriz‐
ing the device (e.g., selecting the resolution of the distance value output, measuring
direction...). After downloading the project planning details to the controller, all device
parameters are stored there.
When the device is replaced, this makes it possible to transmit all device parameters
from the controller to the new device (exception: PROFINET station name).
If the control and the project planning tool support the “Device replacement without
exchangeable medium” PROFINET function and this has been considered during plan‐
ning, the station name is automatically applied during device replacement.
Parameters set via the display or SOPAS ET are generally overwritten with the parame‐
ters defined in the project planning tool. The are also lost as soon as the device is
integrated in a PROFINET network and cyclical data exchange is started.
10.1.1 Generic station description (GSD) file
A generic station description (GSD) file contains a description of the properties of a
PROFINET IO device, e.g., the functions supported by the device or the digital informa‐
tion the controller receives from the device and the format of this information. It defines
modules which can be used to flexibly adapt different control tasks see "GSD modules",
page 54 and see "Module description", page 58.
Bitmap files are also GSD files. The status of the PROFINET IO device is visualized using
these files.
The generic station description as well as the respective bitmaps are needed to plan
a PROFINET IO network. Every device receives an ID number from the PROFIBUS and
PROFINET user organization (PI).
