10.5.2.3 Data transmission
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 the telegram
On the drive side, the sequence of drive objects in the telegram is displayed via a list in
p0978[0...24] where it can also be changed.
You can use the STARTER commissioning tool to display the sequence of drive objects for a
commissioned drive system in online mode in the project navigator under "Drive unit" >
"Communication" > "Telegram configuration".
When you create the configuration on the controller side (e.g. HW Config), the process-data-
capable drive objects for the application are added to the telegram in this sequence.
The following drive objects can exchange process data:
● Control Unit CU_DC
● ENC
● Terminal Board 30 (TB30)
● Terminal Module 15 (TM15)
● Terminal Module 31 (TM31)
● Terminal Module 150 (TM150)
● DC_CTRL
Note
The sequence of drive objects in HW Config must be the same as that in the drive (p0978).
