Data Transfer - Siemens SINAMICS S120 Function Manual

Communication
10.3 Communication via PROFINET IO
Note
You can enter the address data for the internal PROFINET ports X150 P1 and P2 in
STARTER in the expert list using parameters p8920, p8921, p8922 and p8923.
You can enter the address data for the ports of the optional CBE20 module in STARTER in
the expert list using parameters p8940, p8941, p8942 and p8943.
Replacing the CU320-2 DP/PN and CU310-2 PN Control Units (IO device)
If the IP address and device name are stored in non-volatile memory, this data is also
forwarded with the memory card of the Control Unit.
If a complete Control Unit needs to be replaced due to a device or module defect, the new
Control Unit automatically parameterizes and configures using the data on the memory card.
Following this, cyclic exchange of user data is restarted. The memory card allows module
exchange without an IO supervisor when a fault occurs in a PROFINET device.
10.3.1.3

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 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.
