Topology
Line: For the line structure, all nodes are connected in series. The line structure is achieved
via switches which have already been implemented in the PROFINET devices. If a node fails,
communication over the failed node is not possible.
Star: When nodes are connected to a switch with more than 2 PROFINET interfaces, a
star−shaped network topology is automatically formed. If a single PROFINET device fails,
this does not cause a complete network failure as in case of the other structures. The switch
failure only causes a failure of the sub−network.
Ring: In order to increase the availability, you can connect both open ends of a line
structure via a switch. When you parameterise the switch as redundancy manager, it will
make the data be transmitted via an intact network connection in the case of power
failure.
Tree: When several star−shaped structures are interconnected, a tree−shaped network
topology is formed.
GSDML file
Lenze provides you with a GSDML file for your IO−Device. This file is either located on the
enclosed data medium or in the download area of www.lenze.de.
Install the GSDML file in your project planning tool. More information on how to install the
GSDML file can be found in the manual of your project planning tool. For configuration in
your project planning tool, the GSDML file contains all system modules as XML data.
Addressing
In contrast to the PROFIBUS address, each device in PROFINET can be identified
non−ambiguously via its PROFINET interface:
ƒ IP address or MAC address
ƒ Device name
Transmission medium
PROFINET is Ethernet−compatible according to the IEEE standards. The PROFINET IO field
devices are exclusively connected via switches as network components. It is either carried
out as a star−shaped structure via multiple port switches or line−shaped by means of
switched implemented in the field device.
