System Manual
PROFINETIO
PROFINET IO interface
(X1P1R and X1P2R)
The CPU has an X1 interface with two ports (X1P1R and
X1P2R).
• The PROFINETIO interface X1 (defaultP1R) is used to
set up the PROFINET ring or PROFINET network (e.g.
line topology, mixed topology) with the two CPUs
and the IO devices.
• The interface supports PROFINETIO RT (Real-Time)
and PROFINET basic functionality.
Basic PROFINET functionality comprises:
– HMI communication
– Communication with the configuration system
– Communication with a higher-level network
(backbone, router, Internet)
– Communication with another machine or auto
mation cell
PROFINET interface (X2P1) The CPU has an X2 interface with one port (X2P1).
The interface supports PROFINET basic functionality.
H‑Sync interfaces (X3P1
and X4P1)
Die CPU has an X3 interface with one port (X3P1) and an
X4 interface with one port (X4P1).
The X3 and X4 interfaces are reserved for the synchroniz
ation of the two CPUs.
Synchronization modules Make the redundancy connections between the two
CPUs via the synchronization modules with fiber-optic
cables.
You plug each synchronization modules in the X3 and X4
interfaces.
Fiber-optic cables You connect the two synchronization modules in pairs to
each CPU via a fiber-optic cable.
Operation of the CPUs as IO
controllers
IO controller:
As IO controllers the CPUs address the following con
figured IO devices:
• IO devices with system redundancy S2
• IO devices with system redundancy R1 (as of FW ver
sion V3.0)
• Standard IO devices (switched S1 devices)
