PROFINET communication profile
The communication profile defines how participants serially transmit their data via the trans
-
mission 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:
• Real Time 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 module configuration while communication is being estab
-
lished
- I&M data (Identification & Maintenance functions)
- Reading diagnostic information
- Reading I/O data
- Writing device data
Conformance Classes
PROFINET devices are categorized into conformance classes to simplify the evaluation and
selection of the devices for the users. The AMS 348
