4. Download the project to the S7 CPU. Once the download is complete, continue with the
next step.
Note
Because the PN/CAN LINK has not been assigned a PROFINET device name or an IP
address, some errors will occur in the S7 CPU after downloading the project because the
S7 CPU cannot reach the devices. The project download may take a bit longer because the
device cannot be found.
5. In the "Online access" folder, assign the PROFINET device name and the IP address that you
have configured in the project.
6. For operation, set the S7 CPU back to "RUN".
Critical plant state
The Ethernet switch integrated in the PN/CAN LINK is only operational once the PN/CAN LINK
starts up. Restarting the PN/CAN LINK interrupts the Ethernet switch function.
Existing Ethernet connections via the switch are thus interrupted for the duration of the
PN/CAN LINK startup. This can result in critical plant states.
