PROFINET
PROFINET (Process Field Network) is the open Industrial Ethernet Standard from Profibus &
Profinet International (PI) for automation.
Within the context of Totally Integrated Automation (TIA), PROFINET is the systematic
development of the following systems:
● PROFIBUS DP, the established fieldbus
● Industrial Ethernet, the communications bus for the cell level.
Experiences from both systems have been and are being integrated in PROFINET.
PROFINET IO controller
Device via which the connected IO devices are addressed. This means the IO controller
exchanges input and output signals with assigned field devices. The IO controller is often the
controller on which the automation program runs.
PROFINET IO device
Distributed field device assigned to one of the IO controllers.
PROFINET IO Supervisor
PG/PC for commissioning and diagnostics.
PROFIsafe
The PROFIBUS safety profile specifies communication between fail-safe I/O devices and
fail-safe controllers. It is based on the standards for safety-related applications as well as on
the experience of PLC users and manufacturers who are members of PROFIBUS
International (PI). The PROFIBUS safety profile has TÜV and BIA (Institute for Occupational
Safety and Health of the German Social Accident Insurance) certification. The newest
version of the PROFIsafe specification is the Profile for Safety Technology V1.11
specification, published in 07/2001.
Programmable logic controller (PLC)
Controller whose functionality is stored in the control equipment as a software program. The
PLC comprises a CPU, memory, input/output modules, and an internal bus system. The I/O
and the programming language are oriented toward control engineering needs.
Programming device
A compact and transportable PC, suitable for industrial purposes. Its distinguishing feature is
the special hardware and software for SIMATIC programmable logic controllers.
