Synchronization Of A Simotion Device With An Isochronous Dp Master Interface - Siemens SIMOTION Function Manual

Status diagram
For a SIMOTION device without an isochronous DP master interface, the status diagram in
the figure below describes:
● Both synchronization states
● The values of the corresponding system variables
● The state transitions and the associated initiated alarms (TDI#InterruptId), provided they

interface
Prerequisites
1. At least one PROFIBUS interface in the SIMOTION device has been configured as an
2. An interface receives a higher-level bus cycle clock and is configured accordingly, i.e. as
3. The same bus cycle clock must be configured for all isochronously operated interfaces.
Example configuration
The following figures show example configurations for synchronization of a SIMOTION device
which has an isochronous DP master interface with a higher-level bus cycle clock. The
synchronization behavior depends on whether a PROFIBUS DP subnet or a PROFINET IO
subnet supplies the higher-level bus cycle clock.

This prerequisite is always met with SIMOTION D4xx devices; the interface "DP Integrated"
is always configured as an isochronous DP master interface.
