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. 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 the online mode under "Drive unit" > "Communication" >
"Telegram configuration".
When you create the configuration on the controller side (e.g. HWConfig), the process-data-
capable drive objects for the application are added to the telegram in this sequence.
Note
The order of the drive objects
The sequence of drive objects in HW Config must be the same as that in the drive (p0978).
Drive objects after the first zero in p0978 must not be configured in the HW Config.
The structure of the telegram depends on the drive objects taken into account during
configuration. Configurations that do not take into account all of the drive objects in the drive
system are permitted.
