8. Configure the PROFINET IO device ET 200SP HA with the exact same configuration as that of
the IO device ET 200SP HA in the project "Shared-Device-1" in the station "CPU1" (notes from
step 4.).
9. Save and compile the hardware configuration and close the hardware configuration in the
configuration tool and the project.
Result
The shared device is created. You assign the submodules to the configured stations.
Note
Send clock
When using the shared device across multiple projects, make sure that the send clock for the
shared device is set to the same value in the projects. Otherwise, the shared device cannot be
adopted by the IO controller of the configured station.
Assigning submodules
At least one submodule must be assigned to each station.
The submodules must be assigned separately for each station. Note that changes to one station
affect other station(s).
Note
Access rules
A submodule may only be assigned to one IO controller at any given time in the hardware
configuration in the configuration tool. This means that the submodule in slot 4, for example,
can only be assigned to the "CPU1" with the setting "full access"; in "CPU2" the setting for the
submodule in slot 4 must therefore be "- - -" (corresponds to "no access").
1. Open the station of the IO controller "CPU1" of the project "Shared-Device-1" in the hardware
configuration in the configuration tool.
2. Open the properties of the PROFINET IO device.
3. Configure the access to the individual submodules.
4. Save and compile the hardware configuration and close the hardware configuration in the
configuration tool and the project.
5. Open the station of the IO controller "CPU2" of the project "Shared-Device-2" in the hardware
configuration in the configuration tool.
6. Repeat steps 2 to 4.
