You create two redundancy connections between the H-CPUs
with fiber-optic cables using a total of four synchronization
modules (two in each H-CPU).
The following synchronization module versions can be or-
dered:
Sync module 1 GB FO 10 m: for fiber-optic cables up to
•
10 m in length
Sync module 1 GB FO 10 km: for fiber-optic cables up to
•
10 km in length
You connect the two synchronization modules for each CPU in
a pair with a fiber-optic cable. The following lengths of fiber-
optic cables can be ordered:
1 m
•
2 m
•
10 m
•
Up to 10 km (on request)
•
The 4-pin connection plug provides the supply voltage.
The system power supply can be connected to the backplane
bus using a U connector. In the S7-1500R/H redundant sys-
tem, the system power supply does not support diagnostics.
Various models of system power supplies are available:
PS 25 W 24 V DC
•
PS 60 W 24/48/60 V DC
•
PS 60 W 24/48/60 V DC HF
•
Extended retentivity of the PS is not supported in S7-
1500R/H.
PS 60 W 120/230 V AC/DC
•
A power cable connector with coding element and U connector
is included in the scope of delivery for the system power sup-
ply and can be ordered as spare part.
The load power supply (PM) supplies the system power supply
(PS) and central modules (CPU) with 24 V DC.
If you are using load power supplies, we recommend the de-
vices from our SIMATIC series. These devices can be mount-
ed on the mounting rail.
Various models of load power supply are available:
PM 70 W 120/230 V AC
•
PM 190 W 120/230 V AC
•
