11.1
Firmware update
Procedure
1. Set the S7 CPU to "STOP".
2. Initiate the update of the PN/J1939 LINK in the TIA Portal. Depending on the
configuration in the TIA Portal, the PN/J1939 LINK resumes running on its own after a
successful update and waits for configuration information from the S7 controller.
3. For operation, set the S7 CPU back to "RUN".
CAUTION
Critical plant state
The Ethernet switch integrated in PN/J1939 LINK is only operational once the PN/J1939
LINK starts up. Restarting the PN/J1939 LINK interrupts the Ethernet switch function.
Existing Ethernet connections via the switch are thus interrupted for the duration of the
PN/J1939 LINK startup. This can result in critical plant states.
