PROFINET of IEC 61158 has the following properties:
n Full-duplex transfer with 100MBit/s via copper respectively fibre
optics.
n Switched Ethernet
n Auto negotiation (negotiates the transfer parameters)
n Auto crossover (transmission and receipt lines are crossed auto-
matically if necessary)
n Wireless communication via Bluetooth respectively WLAN
n UDP/IP is used as overlaid protocol. UDP means User Datagram
Protocol and contains the unprotected connectionless broadcast
communication within IP.
Like PROFIBUS DP also with PROFINET IO the following devices
are classified according to their tasks:
n IO controller
n IO device
n IO supervisor
The IO controller is equivalent to the master of PROFIBUS. This is
the PLC with PROFINET connection, in which the PLC program runs.
The IO device is a distributed I/O field device, which is connected to
PROFINET. The IO device is equal to the slave of PROFIBUS.
The IO supervisor is an engineering station as e.g. programming unit,
PC or HMI interface for commissioning and diagnostics.
AR (Application Relation) corresponds to a connection to an IO con-
troller or IO supervisor.
From VIPA there is a GSDML files for your IO device available. This
file may either be found on the supplied storage media or at the
download area of www.vipa.com. Please install the GSDML file in
your configuration tool. Details on the installation of the GSDML file
are available from the manual supplied with your configuration tool.
For configuration in your configuration tool every module may be
found in the GSDML file as XML data.
In contrast to the PROFIBUS address in PROFINET each device may
be identified with its PROFINET interface:
n IP address or MAC address
n Device name
PROFINET is compatible to Ethernet in accordance with the IEEE
standards. The connection of the PROFINET IO field devices is
exclusively established via switches as network components. This is
made either as star via multi-port switches or as line by means of
switches, integrated to the field devices.
