Data Transmission - Siemens SINAMICS G150 Operating Instructions Manual

Operation
6.9 Communication via PROFINET IO
Device name (NameOfStation)
When it is shipped, an IO device does not have a device name. An IO device can only be
addressed by an IO controller, for example, for the transfer of project engineering data
(including the IP address) during startup or for user data exchange in cyclic operation, after it
has been assigned a device name with the IO supervisor.
Note
Save device name retentively
The device name must be stored retentively using either STARTER or with the hardware
Config of STEP 7.
Note
Address data for ports
The address data for the internal PROFINET ports X150 P1 and P2 in STARTER can be
entered into the expert list using parameters p8920, p8921, p8922 and p8923.
The address data for the ports of the CBE20 can be entered in STARTER into the expert list
using parameters p8940, p8941, p8942 and p8943.
Replacing Control Unit (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. The memory card allows module
exchange without an IO supervisor when a fault occurs in a PROFINET device.
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.

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. These acyclic services can be utilized by the IO supervisor or IO
controller.
