Procedure - Configuring access to the shared device
The modules and submodules you insert in the shared device are automatically assigned to
the local CPU. To change the assignment, follow these steps:
1.
Select the interface module in the network view or device view of project "Shared-Device-1".
2. Select the "Shared Device" area in the Inspector window.
A table shows which CPU has access to the respective module or submodule for all
configured modules. The default setting is that the local CPU has access to all modules
and submodules.
3. Keep the "PLC1" setting for all modules and submodules that are to remain in the address
range of the local CPU.
Select the setting "---" for all modules and submodules that are to be located in the
address range of the CPU from the "Shared-Device-2" project (PLC2). This means that an
IO controller outside the project is to have access to the module or submodule.
