Configuring networks
4.5 Configuring PROFINET IO with IRT
Procedure overview
Step Description
1 Configuring the NCU (Page 90)
2 Configuring PROFINET IO IRT devices (Page 92)
3 Configuring IO modules or drive telegrams (Page 94)
4 Configuring the input delay for digital input modules (Page 96)
5 Configuring sync domains (Page 97)
6 Compile the configuration and load into the actual hardware (Page 30)
The compiler issues error messages if you use different values for bus cycles. In this case, match the values (Pa-
ge 99).
7 Assigning I/O addresses to the NCU machine data (Page 100)
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 for handling libraries in the TIA Portal can be found in the information
system under the keyword "Library > Fundamentals".
Further information
Further information on the configuration of IRT can be found in the information system of the
TIA Portal at "Configuring IRT communication".
4.5.6

Configuring the NCU

When you operate drives or IO isochronously using NC, make the following SINUMERIK-
specific settings.
If, however, you operate the drives or I/O via the PLC, make the settings as for an S7-300-
CPU. (See online help, keyword "Isochronous mode, configure".)
Requirement
● The devices to be configured have been inserted (at least one NCU and one PROFINET
IO IRT-conform device).
● The isochronous-conform modules and submodules to be configured have been inserted
in the PROFINET IO IRT-conform device.
See also: Isochronous-capable modules identification (Page 86)
● The PROFINET IO IRT-conform devices are interconnected to the NCU with X150.
