If you use PROFINET devices that do not support H-Sync Forwarding in S7-1500R,
1)
additional cycle time increases may occur in system state RUN-Redundant. If the cyclic
program exceeds the cycle monitoring time, the timeout OB (OB 80) may be started. You
can find additional information in the section Start events (Page 153).

Requirement
All PROFINET IO devices assigned to the S7-1500R/H system must support system
•
redundancy S2. These PROFINET IO devices can be located in the PROFINET ring or
they can be separated with a switch.
With S7-1500R/H, all PROFINET devices in the PROFINET ring must support the media
•
redundancy function.
For S7-1500R, the H-Sync forwarding function
•
devices in the PROFINET ring.
The following PROFINET IO devices support system redundancy S2, media redundancy
•
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 200MP IM 155-5 PN HF (6ES7155-5AA01-0AB0), FW version V4.2 or later
– PN/PN coupler (6ES7158-3AD10-0XA0), FW version V4.2 or later
Switches of the product families XC-200, XP-200 and XF-200BA support system redun-
•
dancy S2, media redundancy and H-Sync-Forwarding, for example SCALANCE XC208
(6GK5208-0BA00-2AC2), FW version V4.0 or later.
In STEP 7, "Manager (auto)" is set as the media redundancy role for each of the two R/H
•
CPUs. For all other devices in the PROFINET ring, set "Client" as the media redundancy
role.
PROFINET devices that do not support system redundancy S2 can be located in the
•
PROFINET ring or be separated with a switch.
– Switches without system redundancy S2:
Set the media redundancy role to "Client" over the Web interface.
Configure the ring ports in line with the wiring.
– HMI devices without system redundancy S2:
Set the media redundancy role to "Client" in the HMI configuration.
S7-1500 CPUs: Firmware version V2.5 or later
•
The redundant system does not recognize the S7-1500 CPUs when calculating the max-
imum 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.
System power supply PS or load power supply PM for the R/H CPUs
The use of the PS or PM is optional.
Suitable system power supplies:
PS 25 W 24 V DC (not suitable for CPU 1517H-3 PN)
•
PS 60 W 24/48/60 V DC
•
PS 60 W 24/48/60 V DC HF
•
PS 60 W 120/230 V AC/DC
•
Suitable load power supplies:
PM 70 W 120/230 V AC
•
PM 190 W 120/230 V AC
•
is also recommended for the PROFINET
