6. Select the setting "---" for all modules and submodules that are to be located in the
address range of the CPU from the "Controller1" project (Controller1).
7. Finally, check whether the settings for access are "complementary" for each module or
submodule in both projects. This means that if the local CPU has access in one project,
the option "---" must be set in the other project and vice versa.
Note: The option "---" for the PROFINET interface and therefore for the ports makes the
associated parameters read-only and not changeable. Parameters of the PROFINET
interface and port parameters can only be edited in the project in which the PROFINET
interface is assigned to the local CPU. The ports can be interconnected in both projects
regardless of this.
8. Check whether the same IP address parameters and device name are set for the shared
device in all projects.
Check whether the same S7 subnet ID is set in all projects for the subnet to which the
shared device is connected (subnet properties, "General" area in the Inspector window).
Note
If you make changes to the shared device: Make the same changes in each project on the
shared device. Make
sure that only one IO controller has access to a module or submodule.
