5.1 Requirements
Introduction
Please note the following requirements for use of the S7-1500R/H redundant system.
Hardware requirements
Table 5-1Hardware requirements
Property Requirement
S7-1500R/H CPUs • 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
1)
PROFINET devices • 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
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.
2)
If you use PROFINET devices that do not support H-Sync Forwarding in S7-1500R, additional cycle time increases may occur
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.
