Adjust other settings if required – for example times Ti/To for reading in/outputting data in
isochronous mode.

Note
With these settings, you operate the SINAMICS Integrated as an independent
clock system.
With this setting, you operate the SINAMICS Integrated in isochronous mode
coupled with the clock system of the X142 technology I/Os.
Use this setting if you want to use the technology I/Os isochronously with the
OB servo, for example, for measuring input or output cam applications.
Please note the following:
• You cannot operate the X142 technology I/Os in isochronous mode sepa-
rately from SINAMICS Integrated.
• If you want to operate technology I/Os X142 and SINAMICS Integrated
isochronously at the same time, the coupled isochronous mode must be
set.
Consistency checks ensure that the setting is correct.
With this setting, you operate SINAMICS Integrated in isochronous mode cou-
pled with PROFINET interface X150. SINAMICS Integrated uses the system
clock of PROFINET interface X150.
Use this setting if you need to operate the SIMATIC Drive Controller in isochro-
nous mode at PROFINET IO interface X150, for example, for the connection of
drives or for synchronous operation across PLC.
