Requirements

Introduction
Please note the following requirements for use of the S7-1500R/H redundant system.
Hardware requirements
Table 5-1 Hardware requirements
Property
S7-1500R/H CPUs
PROFINET devices
1) As of FW version V3.0 of the R-CPUs, the firmware between CPU and display is no longer separated. The firmware of the
display is included in the firmware of the R-CPU.
If you use PROFINET devices that do not support H-Sync Forwarding in S7-1500R, additional cycle time increases may occur
2)
in the RUN-Redundant system state. If the cyclic program exceeds the cycle monitoring time, the time error OB (OB 80)
may be started. You can find additional information in the section Events and OBs.

Requirement
• 2 identical R-CPUs or H-CPUs in the redundant system
• Identical article numbers and firmware versions for the two CPUs
• Firmware version display of the R/H-CPUs: As of FW version V2.6
• Media redundancy (MRP)
– All PROFINET devices in the PROFINET ring support the function media redundancy.
– Both CPUs have the media redundancy role "Manager (auto)". All other devices in the
PROFINET ring have the media redundancy role "Client".
• H-Sync forwarding 2) - for PROFINET devices in the PROFINET ring with S7-1500R:
– When you use PROFINET devices with more than two ports (e.g. switch) in the
PROFINET ring of an R-system, then H-Sync Forwarding is mandatory for these devices.
– H-Sync forwarding is recommended for all devices in the PROFINET ring if you are using
PROFINET devices with only 2 ports in the PROFINET ring of an R-system.
• Redundancy:
– With the switched S1 device function, you can operate any standard IO device on the
redundant S7-1500R/H system.
– An IO device must support system redundancy S2 or R1 for uninterrupted exchange of
process data in the event of failure of the primary CPU (primary-backup switchover).
• The following SIMATIC PROFINET IO devices support system redundancy S2, media redund­
ancy and H-Sync forwarding:
– ET 200SP IM 155-6 PN HF (6ES7155-6AU00-0CN0), FW version V4.2 or later
– ET 200SP IM 155-6 PN/2 HF (6ES7155-6AU01-0CN0), FW version V4.2 or later
– ET 200SP IM 155-6 PN/3 HF (6ES7155-6AU30-0CN0), FW version V4.2 or later
– ET 200SP IM 155-6 MF HF (6ES7155-6MU00-0CN0), as of FW version V5.0.1
– ET 200MP (6ES7155-5AA00-0AC0), FW version V4.2 or later
– PN/PN coupler (6ES7158-3AD10-0XA0), FW version V4.2 or later
– PN/MF coupler (6ES7158-3MU10-0XA0), FW version V5.0 or later
