 Net data
Main tasks of the Master-Slave-Communication:
1. Writing and reading of parameters: 2. Controlling the operating process:
• reading faults and diagnostics signals • permanent assignment of control bits and
• reading and changing function values setpoint values
i.e. in set-up mode • permanent reading of status and actual values

parameter data range (PKW) process data range (PZD)

source of main setpoint value of main setpoint

source of control bits logic state of control bits

The data are transferred:

• on request only if necessary • fast and permanently

• with free access to any parameter • with assigned (fixed) “wiring” to the process

acyclic cyclic

via DS47 telegrams via Standard Telegrams

SINAMICS slave on PROFIBUS

STARTER also allows an easy and comfortable integration of a
SINAMICS drive unit into a SIMATIC automation project:

GSD-file from CFC

HW Config

The SINAMICS drive unit as a PROFIBUS slave supports:

¾ the integration into SIMATIC/STARTER and SIMOTION for easy engineering
¾ the cyclic communication with (without) Standard Telegrams / clock synchronous operation for Servo
¾ the acyclic communication for drive parameterization

PLC-side
initially select any kind of Standard Telegram

Drive-configuration with STARTER

Drive-side
The drive tool (STARTER) is opened from the programming tool (STEP 7).
Common data management is provided by using only one project.
By selecting a Standard Telegram, the “interface-wiring“ on the drive is automatically configured (BICO).
By aligning the communication data (via STARTER) data consistency is guaranteed.

In the S7 HW Configuration all Standard Telegrams according to PROFIdrive - Profile V4 are available.
On the drive the automatic BICO-configuration is limited to the telegrams relevant for the selected operating type
(Servo, Vector).
