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
PROFIdrive telegrams are available for implementing cyclic communication via
PROFINET IO.
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.
Using the STARTER commissioning tool you can display the sequence of drive objects for a
commissioned drive system 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 the sequence shown
(see above).
The following drive objects can exchange process data:
● Active Infeed (A_INF)
● Basic Infeed (B_INF)
● Control Unit (CU_S)
● ENC
● Smart Infeed (S_INF)
● SERVO
● Terminal Board 30 (TB30)
● Terminal Module 15 (TM15)
● Terminal Module 31 (TM31)
● Terminal Module 41 (TM41)
● Terminal Module 120 (TM120)
● Terminal Module 150 (TM150)
● VECTOR
