Siemens Simatic S7-1500H - Firmware Functions

What's new in the S7‑1500R/H redundant system System Manual, issue 05/2021 compared to
issue 11/2019
What's new? What are the customer benefits? Where can I find the informa
tion?
CPU 1518HF-4 PN The CPU 1518HF-4 PN expands the R/H-CPU
portfolio with an HF-CPU. The CPU provides the
following advantages:
• Powerful H-CPU with integrated F-function
ality
• The integrated F-functionality processes
standard and safety programs. This allows
fail-safe data to be evaluated in the stand
ard user program. Due to this integration,
the system benefits and the comprehensive
functionality of SIMATIC are also available
for fail-safe applications.
• 3 PROFINET interfaces per CPU

Influence changeover time of
switched S1 devices
As of FW version V2.9, you can influence the
changeover time between disconnection and
return of switched S1 devices after a fail
ure/STOP of the primary CPU.
This function provides the following advant
age:
• Optimization of the changeover time
between disconnection and return of
switched S1 devices

MRP interconnection The MRP interconnection process is an
enhancement of MRP. MRP interconnection
allows the redundant coupling of two or more
rings with MRP in PROFINET networks.
MRP interconnection offers the following
advantages:
• There is no limit to the maximum number
of 50 devices in a ring when setting up
redundant network topologies.
• Monitoring of larger topologies with ring
redundancy.

Simulation of R/H-CPUs PLCSIM Advanced V4.0 supports the simulation
of the R/H-CPUs
• Virtual commissioning of machines with
R/H-CPUs in a plant
• Automated testing of the STEP7 user pro
gram
Simulation provides the following advantages:
• Early error detection and risk minimization
• Shorter commissioning time
• No hardware costs
