Communication
9.4 Communication via PROFINET IO
Function Manual
618 Function Manual, 01/2011, 6SL3097-4AB10-0BP3
9.4.1.2 Data transfer
Properties
The PROFINET interface on a drive unit supports the simultaneous operation of:
● IRT – isochronous real-time Ethernet
● RT – real-time Ethernet
● Standard Ethernet services (TCP/IP, LLDP, UDP and DCP)
PROFIdrive telegram for cyclic data transmission, acyclic services
Telegrams to send and receive process data are available for each drive object of a drive
unit with cyclic process data exchange.
In addition to cyclic data transfer, acyclic services can also be used for parameterizing and
configuring the drive unit. These acyclic services can be utilized by the IO supervisor or IO
controller.
Sequence of drive objects in cyclic data transmission
The sequence of drive objects is displayed via a list in p0978[0...15] where it can also be
changed.
Note
The sequence of drive objects in HW Config must be the same as that in the drive (p0978).
9.4.1.3 General information about PROFINET IO for SINAMICS
General information
PROFINET IO is an open Industrial Ethernet standard for a wide range of production and
process automation applications. PROFINET IO is based on Industrial Ethernet and
observes TCP/IP and IT standards.
Signal processing in real time and determinism is important in industrial networks.
PROFINET IO satisfies these requirements.
The following standards ensure open, multi-vendor systems:
● International standard IEC 61158
PROFINET IO is optimized for high-speed, time-critical data transfers at field level.
