10.1.1 General information about PROFIdrive for SINAMICS
General information
PROFIdrive V4.1 is the PROFIBUS and PROFINET profile for drive technology with a wide
range of applications in production and process automation systems.
PROFIdrive is independent of the bus system used (PROFIBUS, PROFINET).
Note
PROFIdrive for drive technology is standardized and described in the following document:

As bus node Active Passive
Send messages Permitted without external
request
Only possible on request by
master
Receive messages Possible with no restrictions Only receive and acknowledge
permitted
● Controller (PROFIBUS: Master Class 1, PROFINET IO: IO Controller)
This is typically a higher-level control in which the automation program runs.
Example: SIMATIC S7 and SIMOTION
● Supervisor (PROFIBUS: Master Class 2, PROFINET IO: IO Supervisor)
Devices for configuration, commissioning, operator control and monitoring during bus
operation. Devices that only non-cyclically exchange data with Drive Units and
Controllers.
