Communication channels for PROFINET
PROFINET connection channels
● A Control Unit has an integrated Ethernet interface (X127).
● The PROFINET versions CU320-2 PN and CU310-2 PN each have a PROFINET
interface (X150) with two onboard ports: P1 and P2
● A CU320-2 PN or a CU310-2 PN Control Unit can simultaneously establish a total of eight
acyclic connections (e.g. S7) via the integrated PROFINET interfaces.
Control Unit with CBE20
A Communication Board can be optionally inserted in the CU320-2 PN/DP Control Unit:
● The CBE20 Communication Board (X1400) is a PROFINET switch with 4 additional
PROFINET ports.
Notes
Note
PROFINET routing
Routing is not possible between the onboard interfaces X127 and X150
– or between the
onboard interfaces of the Control Unit 320
-2 PN and an inserted CBE20 (X1400).
Note
PROFINET interfaces on the CU320-2 PN with CBE20
The integrated PROFINET interface of the CU320
-2 PN is independent of the optionally
inserted CBE20 module. The two PROFINET interfaces are not connected with each other.
Routing is not possible between the two PROFINE
T interfaces.
Note
Ring topology
When connecting the ports, it must be ensured that for standard applications a ring topology
is not created. Additional information on ring topologies can be found in Section
