Sync X11 (green)
2)
Sync status of
PROFINET interface
This LED indicates the synchronization status of the PROFINET interface
X11.
LED - OFF The PROFINET interface has not synchronized yet to the send cycle of
IRT or PROFINET with IRT has not been configured (e.g. only RT or
TCP/IP operation). If no PROFINET IO with IRT has been configured,
then generally there is no synchronization of the PROFINET interface. If
isochronous data has been configured for the SIMOTION device, the
PROFINET interface generates a local substitute cycle of the same size
as the configured send cycle of IRT, as long as no synchronization has
been performed to the send cycle of IRT:
 The task system of SIMOTION has synchronized to the local
substitute cycle of the PROFINET interface.
 DP interfaces, if configured as isochronous, are synchronized to the
local substitute cycle of the PROFINET interface.
LED - flashing (2
Hz)
The PROFINET interface has synchronized to the send cycle of IRT. If
isochronous data has been configured for SIMOTION, then the following
applies:
 The task system of SIMOTION has synchronized to the send cycle of
IRT.
 DP interfaces, if configured as isochronous, have not synchronized
yet to the send cycle of IRT.
LED - ON The PROFINET interface has synchronized to the send cycle of IRT. If
isochronous data has been configured, then the following applies:
 The task system of SIMOTION has synchronized to the send cycle of
IRT.
 DP interfaces, if configured as isochronous, are synchronized to the
send cycle of IRT.
If no isochronous data has been configured for SIMOTION, this state
indicates that only the PROFINET interface has synchronized to the send
cycle of IRT. The PROFINET interface is then used to forward the data.
Isochronous data means that data is exchanged with a further device on
PROFINET with configured RT class IRT and isochronous
application/device.
1) Minimum flashing duration 3 s
2) If no PROFINET IO with IRT has been configured, then generally no synchronization will be made to the send cycle.
Note
During ramp-up of the SIMOTION C, the LEDs on the housing front are briefly illuminated.
You can carry out a detailed diagnosis with a programming device or PC and the
