Activating system redundancy type R1 for distributed I/O
The system redundancy type R1 for distributed I/O can be activated through a license key. This
license key must be transferred onto the SEC of the CPU. You can perform the activation
without swapping the SEC.
You can activate system redundancy type R1 for distributed I/O as the upgrade of the system
expansion card of a CPU 410-5H.
You can find information on this in the documentation
Support and Diagnostics.
Response to failure
The following applies when a CPU or PROFINET cable fails:
The IO devices continue to be available in the PROFINET IO system.
Maintenance and service
One of the following functions is possible in runtime:
● Connecting and removing IO devices
● Replacing PROFINET cables
● Replacing a CPU

③
System redundancy
(1 subnet)
The PROFINET IO sys‐
tem begins and ends at
an IO controller.
Possible
If a PROFINET IO system is created at each PN-IO connection of the CPU, a
newly inserted interface module is automatically connected to both PROFINET
IO systems of the CPU.
The nodes on the fieldbus (PROFINET IO) must be assigned unique names.
● Network1:
CPU (0) X5 port 1 +
CPU (1) X5 port 1
④
System redundancy
(2 subnets in a line struc‐
ture)
An interface module is connected to each of the two
IO controllers.
The PROFINET IO systems can be created in a sub‐
net.
● Network1:
CPU (0) X5 port 1
● Network2:
CPU (1) X5 port 1

System redundancy
+ Media redundancy
(2 subnets in a ring struc‐
ture)
Yes: The subnet ring is
closed by the MRP con‐
nection to the same CPU.
● Network1:
CPU (0) X5 port 1 +
CPU (0) X5 port 2
● Network2:
CPU (1) X5 port 1 +
CPU (1) X5 port 2
