Data Transmission - Siemens SINAMICS DCM Operating Instructions Manual

Descriptions of functions
10.5 Communication via PROFINET IO
Note
If the network is part of an existing Ethernet company network, obtain the information
(IP address) from your network administrator.
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
The device name must be stored retentively either with STARTER or with HW Config of
STEP 7.
Note
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 Control Unit (CUD) (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.

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)
