3 System Description
The fieldbus has been established for many years in automation.
A fieldbus such as PROFIBUS assists in the transmission of local input and
output signals. These communication systems have been further developed to the
extent that, today, perfected technologies with optimized power are available.
ETHERNET-based communication systems are continuously gaining more
meaning. These systems utilize the advantages of information technology, with
such standards as ETHERNET or TCP/IP. Thus, improved communication
possibilities are being unveiled in automation – including, for example, the
integration of devices from the field level to the company management level using
a fieldbus. However, even the administration of the network with SNMP and the
use of web services for the diagnosis and maintenance of devices are
characteristics of an ETHERNET-based fieldbus system.
PROFINET is an open and cross-vendor automation standard from the
PROFIBUS User Organization. This fieldbus uses the experiences with
PROFIBUS as well as the standardized functionalities from ETHERNET.
Characteristics of PROFINET
• Communication system for factory and process automation
• Integration of local field devices
• Real-time cabability (RT) and isochronic realtime cabability (IRT)
• Synchronous uses (motion control)
• Diagnostic capability of controller and device
• Network administration and diagnostics with IT services
• Cross-vendor engineering
• Safety-oriented communication (PROFIsafe)
• Uniform communication at all levels
