Connecting PROFINET
Connecting PROFINET
PROFINET connection
Connect Ethernet cable according to PROFINET
specification to higher-level controller and / or the next
PROFINET node
①.
Use a shielded Ethernet cable with shielded connect-
or for the connection.
We recommend RJ45 connectors from the Siemens
FastConnect system as connectors for the Ethernet
cabling.
Always apply the shields of the PROFINET Ethernet
cable at both ends.
①
Ethernet connections for PROFINET
② Retaining collar
Note
In order to increase the mechanical stability, optimized retaining collars
② for the two
Ethernet connections are attached to the lower part of the PN/M
-Bus LINK enclosure in the
factory state. These retaining collars are intended for the Siemens FastConne
ct 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/M-Bus LINK is only operational once the PN/M-Bus
LINK starts up. Restarting the PN/M-Bus LINK interrupts the Ethernet switch function.
Existing Ethernet connections via the switch are thus interrupted for the duration of the
PN/M-Bus LINK startup. This can result in critical plant states.
