Configuring Communication To The Control - Siemens SINAMICS G120 Original Instructions Manual

Recommended PROFIBUS connectors
We recommend connectors with the following order numbers for connecting the PROFIBUS
cable:
● 6GK1500-0FC10
● 6GK1500-0EA02
Pin assignment at the inverter
For the pin assignment at the inverter refer to Section Interfaces, connectors, switches,
control terminals, LEDs on the CU (Page 60).
Communication with the controller, even when the supply voltage on the Power Module is
switched off
You must supply the Control Unit with 24 V DC at terminals 31 and 32 if you wish to maintain
communication with the control system when the line voltage is switched off.
In the case of short interruptions of the 24 V voltage supply, the inverter may report a fault
without communications with the controller being interrupted.

Configuring communication to the control

To configure communication between the inverter and control system, you generally require
the description file GSD of the inverter.
When STEP 7 and STARTER are installed, you do not need GSD.
Procedure
Proceed as follows to configure communication to the control system using GSD:
1. Obtain the GSD file of the inverter.
2. Import the GSD into the configuring tool of your control system.
3. Configure the communication between the control and the inverter in your control.
You have configured the communication to the control system.

You have two options:
– You can find the GSD of the SINAMICS inverter on the Internet
(http://support.automation.siemens.com/WW/view/en/22339653/133100).
– The GSD is saved in the inverter. If you insert the memory card in the inverter and set
p0804 = 12 , the inverter writes the GSD to the /SIEMENS/SINAMICS/DATA/CFG
folder on the memory card.
