PROFINET interface – basic configuration
As a rule, the BPS is configured via the PROFINET interface. Parameter changes for test purposes and
extended configurations for the timing for the position and velocity measurements can be performed via
the webConfig tool (see chapter 9).
8.1
General information on PROFINET
The BPS is designed as a PROFINET-RT device (Real Time; acc. to IEEE 802.3). It supports a transmis
-
sion rate of up to 100 Mbit/s (100Base TX/FX), full duplex, as well as auto-negotiation and auto-crossover.
• The functionality of the BPS is defined via parameter sets which are organized in modules. The mod
-
ules are part of the Generic Station Description Markup Language (GSDML) file.
• Each BPS has a unique MAC address (Media Access Control) that is specified on the name plate.
The MAC address (MAC-ID) is linked to an IP address during the course of configuration.
• The Simatic Manager for creation of PROFINET networks links the IP address to a freely selectable
device name which may only exist once in the network.

communication profile
The PROFINET communication profile defines how participants serially transmit their data via the trans
-
mission medium. Data exchange with the devices occurs primarily cyclically. For configuration, operation,
observation and alarm handling, acyclic communication services are, however, used as well.
Depending on the communication requirements, PROFINET offers suitable protocols and transfer
methods:
• Real Time communication (RT) via prioritized Ethernet frames:
• Cyclical process data (I/O data stored in the I/O area of the control)
• Alarms
• Clock synchronization
• Neighborhood information
• Address assignment/address resolution via DCP
• TCP/UDP/IP communication via standard Ethernet TCP/UDP/IP frames:
• Establishing communication
• Acyclic data exchange, i.e., transfer of various types of information:
Parameters for the module configuration while communication is being established
I&M data (Identification & Maintenance functions)
Reading diagnostic information
Reading I/O data
Writing device data
NOTICE
Observe for the configuration of PROFINET devices!
Always perform the basic configuration using the Generic Station Description Markup Language
(GSDML) file.
Download the appropriate file from the Internet.
In process operation, only the parameters in the PROFINET modules set via the GSDML file or the
PROFINET default presets are in effect. Parameter changes made via the webConfig tool (see
chapter 9) have no effect in PROFINET.
If you switch the BPS to the
Service
operating mode via the webConfig tool, the BPS is disconnected
from the PROFINET. All parameters set via the GSDML file initially remain in effect. Parameter chang
-
es can now be made via the webConfig tool for test purposes.
Settings configured with the webConfig tool are overwritten by the PROFINET master with the settings
made via the GSDML file upon connection to PROFINET or after deactivation of the
Service
operating
mode.
Configuration data is saved in the device and in the connection hood.
