Procedure - Creating project 1
To create the first project with a shared device, follow these steps:
1. Start STEP 7.
2. Create a new project with the name "Shared-Device-1".
3. Insert, for example, a CPU 1513-1 PN from the hardware catalog in the network view.
Name it "PLC1".
4. Insert an IO device with the "Shared device" function from the hardware catalog.
5. Assign the IO controller "PLC1" to the IO device.
6. Double-click the IO device and insert all required modules and submodules from the
hardware catalog in the device overview table.
7. Assign the module parameters.
8. Save the project.
Procedure - Creating project 2
To create the second project with a shared device, follow these steps:
1. Start STEP 7 once again.
A new instance of STEP 7 opens.
2. In the new instance, create a new project with the name "Shared-Device-2".
3. Insert, for example, a CPU 1513-1 PN in the network view. Name it "PLC2".
4. Copy the IO device from the project "Shared-Device-1" and insert it in the network view of
project "Shared-Device-2".
5. Assign the IO controller "PLC2" to the IO device.
6. Save the project.
Both projects now have an identically structured IO device that must be configured in the
next step for the different types of IO controller access.
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.
