Configuring Additional Drives On Profinet (X150) As Isochronous - Siemens SIMATIC S7-1500 System Manual

Setting the clock system
You have configured the technology I/Os as isochronous. Next, set the clock system.
Make the following settings in accordance with whether you are operating the X142
technology I/Os in independent or coupled isochronous mode:
• For independent isochronous mode or if the X142 technology I/Os are the leading clock
system
– Set the required cycle time.
– Assign the "MC Servo" OB the clock system of the technology I/Os.
Note
You cannot operate the X142 technology I/Os in isochronous mode separately 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.
• For coupled isochronous mode:
– Assign the leading clock system to the clock system of the technology I/Os.

Configuring additional drives on PROFINET (X150) as isochronous

Requirement
• STEP 7, V16 or higher
• SINAMICS Startdrive, V16 or higher
You can import drives that are not integrated in the TIA Portal via Startdrive using GSD files
(generic station description). To do so, install the drive in the "Options" menu as a device
description file (GSD).
Adding a drive and frame to the device configuration
1. Add the required drive system in the network view, for example, SINAMICS S120 CU320-
2 PN.
2. Open the device view of the drive system and configure the drive objects.
You can find the relevant details in the SINAMICS S120 with Startdrive commissioning
manual (https://support.industry.siemens.com/cs/ww/en/view/109781583).
3. Open the network view. Assign the drive system to the PROFINET interface [X150] of the
CPU.
4. Open the topology view. Interconnect the port of the drive system as in the real
configuration with the port of the CPU.
