Siemens SINUMERIK 840D sl Configuration Manual page 87

● The "Information" section does not explicitly list whether drive telegrams (e.g. SIEMENS
telegram 136) support isochronous mode. The compiler will issue an error message if you
use an isochronous telegram without activating isochronous mode for the associated
header module.
● A listing of isochronous-conform PROFINET controllers and PROFINET devices is
contained in the Service & Support portal:
– Which IO controllers and IO devices support the IRT [...] functions and isochronous
– Which SIMATIC S7 components and which drives support isochronous mode?
The associated hardware documentation specifies whether a PROFIBUS controller or
device is isochronous-conform.
Note
Differences for devices based on device description files (DDF)
A description of the functionality is also contained in the "Information" section for DDF
devices. The following differences, however, exist for the configuring:
• GSD devices are not contained in the same folder as standard devices in the hardware
catalog. The SINAMICS S120/S150 CU320-2, for example, are not found under "Field
devices", but rather under "Further field devices > PROFINET IO > Drives > Siemens AG
> SINAMICS".
• To insert modules or submodules for a GSD device, you must use the device overview
rather than the device view.
