Property
Load current supply PM
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.
Special case: Operating R/H CPU individually
You can operate an R/H CPU as a single CPU. If you do, please note the following:
• You always configure 2 R-CPUs or H-CPUs for S7-1500R/H, even if you only set up one CPU.
• The MAINT LED on the CPU is always yellow (maintenance demanded):
– The R/H system is not in redundant mode.
– No partner CPU was found.
S7-1500R/H redundant system
System Manual, 11/2022, A5E41814787-AD
Requirement
• The following SIMATIC PROFINET IO devices support system redundancy R1, media redund­
ancy:
– ET 200SP IM 155-6 PN R1 (6ES7155-6AU00-0HM0), FW version V6.0. or later. A list of
compatible I/O modules for the IM 155-6 PN R1 interface module can be found in the
Product information for the documentation of the ET 200SP
(https://support.industry.siemens.com/cs/en/en/view/73021864) distributed I/O system.
The R1 capability is also specified in the technical specifications of the I/O modules.
– ET 200SP HA IM 155-6 PN HA (6DL1155-6AU00-0PM0) as of FW version V1.2
– ET 200iSP IM 152-1 PN for ET200iSP for standard and redundant operation
(6ES7152-1BA00-0AB0), as of FW version V1.0
• The following switch product families support system redundancy S2, media redundancy,
and H-Sync forwarding:
– XC-200, XP-200 and XF-200BA e.g. SCALANCE XC208 (6GK5208-0BA00-2AC2), as of
FW version V4.0
– XM-400 and XR-500, as of FW version V6.3.0
• S7-1500 CPUs: Firmware version V2.5 or later
The redundant system in STEP 7 does not recognize the S7-1500 CPUs when calculating
the maximum number of IO devices within and outside the PROFINET ring. If you use
S7-1500 CPUs, you will have to check the maximum number yourself.
• SINAMICS S120 PROFINET Control Unit (CU310-2 PN or CU320-2 PN) support system
redundancy S2, media redundancy and H-Sync forwarding, FW version V5.2 or later.
Load current supply PM for the R/H CPUs
The use of the PM is optional.
Suitable load current supplies:
• PM 70 W 120/230 V AC
• PM 190 W 120/230 V AC
