Step Description
4 Configuring sync domains (Page 110)
5 Compile the configuration and load into the actual hardware (Page 39)
The compiler issues error messages if you use different values for bus cycles.
In this case, match the values
(Page 111).
6 Assigning drive addresses to the NCU machine data (Page 112)
Note
Reusing configured drives or devices in other projects
You
can copy preconfigured and configured drives or devices with drag-and-drop into a global
library. In this manner, you can insert them later together with the made settings into another
project and so save configuration effort.
Further information on handling libraries in the TIA Portal can be found in the online help under
"Library > Fundamentals".

information on the configuration of IRT can be found in the TIA Portal online help under
"Configuring IRT communication".
5.5.5 Configuring I/O used by NC isochronously
The procedure for configuring isochronous NC I/O is described below.
If, instead, you want to operate I/O isochronously via the PLC, proceed as for a CPU S7-300.
(Use the OB61 as isochronous alarm OB or the TPA1 as process image, and do not enter the
I/O addresses in the machine data.)
If, rather than non-NC I/O, you want to configure NC drives isochronously, proceed as
described in the associated section (Page 101).
Requirement
● The devices to be configured have been inserted (at least one NCU and one PROFINET IO
IRT-conform device).
● The modules to be configured have been inserted in the PROFINET IO IRT-conform device.
See also Isochronous-capable modules identification (Page 99)
● The PROFINET IO IRT-conform devices are interconnected to the NCU with X150.
Note
Concurrent operation of devices with and without clock synchronization
When you configure devices that do not participate on the IRT communication, observe
the rules for sync domains for PROFINET IO IRT
(Page 110).
