Connecting PROFINET
Connecting PROFINET
PROFINET connector
Connect Ethernet cable according to
PROFINET specification to higher-level control-
ler and / or the next PROFINET node ①.
Use a shielded Ethernet cable with shielded
connector for the connection.
We recommend RJ45 connectors from the Sie-
mens FastConnect system as connectors for the
Ethernet cabling.
Always apply the shields of the PROFINET
Ethernet cable at both ends.
①
Ethernet connector
② Securing collar
Note
In order to increase the mechanical stability, optimized securing collars
② for the two
Ethernet connections are attached to th
e lower part of the PN/J1939 LINK enclosure in the
factory state. These securing collars are intended for the Siemens FastConnect connectors.
NOTICE
Make sure you observe the minimum bending radius of the Ethernet cable; otherwise the
shield effect of the cable shield may be impaired. There is also the risk that the cable shield
breaks.
NOTICE
EMC stability is only guaranteed with shielded PROFINET cables.
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.
