CPU 1518HF-4 PN supports the following firmware functions:
Function
Description
Additional information
CPU redundancy
There are two duplicate CPUs that synchronize their
data via two duplex fiber-optic cables, which connect
the CPUs directly to each other via plug-in synchroniza-
tion modules. If one of the CPUs fails, the other CPU
retains control of the process.

tem Manual
Safety Integrated
The integrated F-functionality processes standard and
safety programs.
This allows fail-safe data to be evaluated in the standard
user program. As a result of the integration, the system
advantages and the extensive functionality of SIMATIC
are also available for fail-safe applications.
The F-CPU is certified for use in safety mode up to:
•
Safety Integrity Level SIL3 acc. to IEC 61508
•
Performance Level (PL) e and Category 4 according
to ISO 13849-1:2006 or according to EN ISO 13849-
1
Additional password protection for F-configuration and
F-program is set up for IT security.

gramming and operating manual
Integrated system diag-
nostics
The system automatically generates the messages for
the system diagnostics and outputs these messages via
a programming device/PC, HMI device or the integrated
display. System diagnostics information is also available
when the CPUs are in operating state STOP.

Integrated trace func-
tionality
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 ex-
ample, drive parameters or system and user tags of a
CPU.
Trace and logic analyzer functions are suitable for moni-
toring 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.
