Basics Profinet IO
Profinet IO uses fast Ethernet technology as the physical transfer medium. The system is
suitable for the high-speed transfer of I/O data and enables requirements data, parame-
ters and IT functions to be transferred down a single line. In the case of Profinet IO,
decentralised field devices (Profinet IO devices) are integrated into the configuration tool
via a device description. The field device properties are described in a GSD file. This file
contains all the necessary information, such as communications parameters, plug-in
modules and their parameters and possible diagnostic messages.
Profinet IO uses a "provider-consumer model" that supports the communication relati-
onships between participants with the same access rights on the Ethernet network. The
provider sends its data without waiting for a request from the communication partner.
As well as the cyclical exchange of user data, Profinet offers additional functions for the
transfer of diagnoses, parameters and alarms.
Anybus-S Profinet bus module
The Profinet bus module works as a Profinet IO device on the Profinet. It supports a
maximum of 2,600 bytes of I/O and parameter data. The IP address settings are set
when configuring the Profinet IO controller and later transferred to the module during
start-up of the IO controller using the DCP protocol.
As well as supporting Profinet protocol functions, the module also supports industrial IT
functions.
Device concept The AB Profibus interface includes a UBST 1 PC board with a piggy-backed Anybus-S
Profinet bus module. All the information required for a Profinet connection is stored on
the CFM on the UBST 1 PC board.
