Procedure overview
Step Description
1 Configuring the NCU (Page 103)
2 Configuring PROFINET IO IRT devices (Page 104)
3 Configuring IO modules or drive telegrams (Page 106)
4 Configuring the input delay for digital input modules (Page 109)
5 Configuring sync domains (Page 110)
6 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).
7 Assigning I/O addresses to the NCU machine data (Page 113)
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".
5.5.6
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 99)
● The PROFINET IO IRT-conform devices are interconnected to the NCU with X150.
