5.3 Shared device
PROFINET with STEP 7 V15
148 Function Manual, 12/2017, A5E03444486-AH
In each of the projects involved, you define which transfer areas are assigned exclusively to
the higher-level IO controller (default setting: all). You set the other transfer areas to "---" (not
assigned). As a result of this setting, the local IO controller has no access to this transfer
area and it can therefore be assigned to another IO controller in another project.
Figure 5-25 Setting the access to the shared I-device.
You adapt the addresses from the view of the IO controller in the device overview. To open
the device overview, double-click the I-device.
