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 PROFINET 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 Media
redundancy (Page 842).
