"Industrial cybersecu-
rity" section
Due to the digitalization and increasing networking
of machines and industrial plants, the risk of cyber
attacks is also growing. Appropriate protective
measures are therefore mandatory, particularly in
the case of critical infrastructure facilities.
The section contains the following information:
• Basic information on the subject of industrial
cybersecurity
• Measures to protect individual components and
the entire system against manipulation and un-
wanted access.

Syslog messages
As of TIA Portal version V19 and FW version V3.1,
you can forward the syslog messages of an R/H-CPU
to a syslog server.
Power supply modules
System power supplies (PS) supply the internal
electronics of the S7-1500R/H modules with power
via the backplane bus. The following system power
supply modules are supported:
• PS 25W 24V DC
• PS 60W 24/48/60V DC
• PS 60 W 120/230V AC/DC
The redundant design of system power supply
modules in the H-CPUs increases the availability of
the supply voltage. If a PS (or supply voltage) fails,
the H-CPU (with the central CPs) remains in the
RUN-Redundant operating state.

Communications
processors CPs
The CPs relieve the R/H CPUs from communication
tasks and enable further communication connec-
tions:
• To the automation level
• To the IT world
The redundant design of the CPs (per R/H CPU)
increases the availability of the redundant system
for communication tasks. As of FW version V3.1, the
S7-1500R/H redundant system supports the
CP 1543-1 communications processor:
• S7-1500R: max. 2 CPs per R-CPU
• S7-1500H: max. 6 CPs per H-CPU
• As of the System overview
(Page 63) section
• CP 1543-1
