Description
Additional information
CPU redundancy
There are two duplicate CPUs that synchronize their
data via redundancy connections within a PROFINET
ring. If one of the CPUs fails, the other CPU retains
control of the process.

Manual
Integrated system diag-
nostics
The system automatically generates the messages
for the system diagnostics and outputs these mes-
sages via a programming device/PC, HMI device or
the integrated display. System diagnostics infor-
mation is also available when the CPUs are in oper-
ating state STOP.

Integrated trace function-
ality
Trace functionality supports you in troubleshooting
and/or optimizing the user program.
You record device tags and evaluate the recordings
with the trace and logic analyzer function. Tags are,
for example, drive parameters or system and user
tags of a CPU.
Trace and logic analyzer functions are suitable for
monitoring highly dynamic processes.
Note: Note that the S7-1500R/H redundant system
supports recording of measurements. However,
saving the measurements to the SIMATIC memory
card is not supported.

PROFINET IO
System redundancy S2 All IO devices are connected redundantly in the re-
dundant S7 1500R/H system. All IO devices as-
signed to the system must therefore support system
redundancy S2.
If the role of the CPUs changes, the new primary
CPU takes over the PROFINET IO communication.
