Communication PROFIBUS DP/PROFINET IO 10.3 Communications via PROFINET IO

References

For a description of the CBE20 and how you can use it in the drive, please refer to the manual GH1 "Control Units".

The connection of a SINAMICS S120 with CBE20 to a PROFINET IO network is described in detail in the System Manual "SIMOTION SCOUT Communication".

Clock generation

The SINAMICS S120 with CBE20 can only act as a sync slave within a PROFINET IO network.

CBE20 module is plugged in CU320:

The cyclic DP interface is disabled.

Transmission type IRT, device is sync slave and isochronous, clock is applied to bus: CBE20 synchronizes, providing the clock for the CU320.

RT or IRT (option "not isochronous") has been configured. The SINAMICS does not use a local clock (clock configured in SINAMICS).

No CBE20 module plugged but configured:

SINAMICS uses local clock (clock configured in SINAMICS), no data exchange via PROFINET, alarm A1487 "Topology fault" is issued.

Access via PROFINET is not available.

Telegrams

The following PROFIdrive telegrams can be selected for PROFINET IO communication:

isochronous standard telegrams 1-6, 20

Telegram 102-106, 352, 370

Telegram 999

DCP flashing

This function is used to check the correct assignment to a module and its interfaces. This function is supported by a SINAMICS S120 from FW 2.4 with plugged CBE20.

1.In HW Config or STEP7 Manager, select the menu item "Target system" > "Ethernet" > "Edit Ethernet node".

2.The "Edit Ethernet node" dialog box opens.

3.Click on the "Browse" button.

4.The "Browse Network" dialog box opens and displays the connected nodes.

5.After the SINAMICS S120 with CBE20 has been selected as a node, activate the "DCP flashing" function by means of the "Flash" button.

The DCP flashing will be effective on the RDY LED (READY LED 2Hz, green/orange or red/orange) on the CPU320.

The LED will continue to flash as long as the dialog is open. When the dialog is closed, the LED will go out automatically. The function is available as of STEP7 V5.3 SP1 via Ethernet.
