PROFINET communication profile
The
communication profile
defines how participants serially transmit their data via the
transmission medium.
The
PROFINET
communication profile is designed for efficient data exchange on the field
level. The data exchange with the devices is mainly
cyclical
. For the configuration,
operation, monitoring and alarm handling, however,
acyclic
communication services are
also used.
Depending on the communication requirements, PROFINET offers suitable protocols and
transfer methods:
•
R
eal
T
ime communication (RT) via prioritized Ethernet frames for
• Cyclical process data (I/O data stored in the I/O area of the control)
• Alarms
• Clock synchronization
• Neighborhood information
• Address assignment/address resolution via DCP
• TCP/UDP/IP communication via standard Ethernet TCP/UDP/IP frames for
• Establishing communication and
• Acyclic data exchange, and also for the transfer of various information types such as:
- Parameters for the configuration of the modules during the establishment of the
communication
- I&M data (Identification & Maintenance functions)
- Reading diagnostic information
- Reading I/O data
- Writing device data
