n Wireless communication via Bluetooth respectively WLAN
n UDP/IP is used as overlaid protocol. UDP means User Datagram Protocol and con-
tains the unprotected connectionless broadcast communication within IP.
Like PROFIBUS DP also with PROFINET IO the following devices are classified
according to their tasks:
IO controller
n
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 inter-
face for commissioning and diagnostics.
AR (Application Relation) corresponds to a connection to an IO controller or IO super-
visor.
API means Application Process Identifier and defines besides Slot and Subslot a fur-
n
ther addressing level.
n With this additional addressing mode with using of different applications, the overlap-
ping of data areas can be prevented.
n Currently PROFINET IO devices from VIPA support API 0.
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 con-
nection of the PROFINET IO field devices is exclusively established via switches as net-
work components. This is made either as star via multi-port switches or as line by means
of switches, integrated to the field devices.
