5.2 Extending a PROFIdrive message frame

Connection of the SINAMICS S120 to the Technology CPU

5.2.2 Extending a message frame by creating additional components

Introduction

For example, to make the integrated digital input/outputs of the SINAMICS S120 available to

the Technology CPU, the input information must be transferred via the PROFIBUS DP

(DRIVE). This requires the creation of an additional PROFIdrive message frame for the

control unit.

Procedure

To create an additional PROFIdrive message frame for the control unit, follow these steps:

1. Open the message frame configuration of SINAMICS S120.

2. Perform an alignment with HW Config by clicking "Align message frame with HW Config:

Set up addresses".

3. Ensure that no I/O addresses have been entered in the "Control Unit" line.

4. Note for the subsequent steps the object number of the objects that have not yet been

connected with the PROFIBUS. This sequence and also the position are required for the

address assignment in HW Config.

In our example, the following object numbers must be noted:

– Object 3 - TB30

– Object 4 - Control Unit

Note

The "Configuration" window must be closed after the alignment. Otherwise

subsequent changes in the hardware configuration will not be considered and may be

discarded.
