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).
