PROFINET-IO communication profile
The
communication profile
defines how participants serially transmit their data via the
transmission medium.
The
PROFINET-IO
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-IO 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 0-4 data (Identification & Maintenance functions)
- Reading diagnostic information
- Reading I/O data
- Writing device data
