Communication PROFIBUS DP/PROFINET IO 10.2 Communication via PROFIBUS DP

The bus terminating resistors in the PROFIBUS plugs must be set as follows:

–First and last nodes in the line switch on terminating resistor

–Other nodes in the line: switch out terminating resistor

●Shielding for the PROFIBUS cables

The cable shield in the plug must be connected at both ends with the greatest possible surface area.

10.2.2.2Commissioning procedure

Preconditions and assumptions for commissioning

PROFIBUS slave

●The PROFIBUS address to be set for the application is known.

●The telegram type for each drive object is known by the application. PROFIBUS master

●The communication properties of the SINAMICS S120 slave must be available in the master (GSD file or drive ES slave OM).

Commissioning steps (example with SIMATIC S7)

1.Set the PROFIBUS address on the slave.

2.Set the telegram type on the slave.

3.Carry out the following in HW Config:

–Connect the drive to PROFIBUS and assign an address.

–Set the telegram type.

The same telegram type as on the slave should be set for every drive object exchanging process data via PROFIBUS.

The master can send more process data than the slave uses. A telegram with a larger PZD number than is assigned for the drive object STARTER can be configured on the master. The PZDs not supplied by the drive object are filled with zeros.

The setting "without PZD" can be defined on a node or object (e.g. infeed controlled via terminals).

4.The I/O addresses must be assigned in accordance with the user program.

The standard slave diagnostics can be read online in the HW Config.
