Maintenance And Service; Firmware Update; Replacing Pn/J1939 Link - Siemens SIMATIC PN/J1939 LINK Operating Instructions Manual

Maintenance and service

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".
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.
