Requirements For Communication Via Profibus - Siemens SINAMICS GM150 Operating And Installation Instructions

Start-up
7.2 Description and configuration of the PROFIBUS interface
If you set the PROFIBUS address using the DIP switches S1 to S7, the parameter p0918 is
read-only. The parameter shows the set address of the control unit. If the address is changed,
the new setting does not become effective until the CU320 Control Unit is switched on.
Example of setting the PROFIBUS address using DIP switches
In this example, PROFIBUS address 37 is set.
Significance
Note
The PROFIBUS address switches have a default setting of 0 or 127 (set via parameter p0918).
7.2.5

Requirements for communication via PROFIBUS

To further process the PZD data internally, the PROFIBUS master must always send a 1 in
the eleventh bit (bit 10) of the first control word (control by PLC). It is not sufficient to
interconnect parameter p854 permanently with a 1.
This also applies to slave-to-slave communication between multiple slaves (drive with DC
master as an excitation device). The eleventh bit (bit 10) must be preset to 1 in the first control
word of the master on the drive. This also applies when no other master control commands
are in use and slaves are communicating by direct slave-to-slave data exchange only.
