What are the customer benefits?
As of FW version V3.0, the S7-1500H redundant
system supports PROFINET system redundancy R1:
• ET200SP IM 155-6 PN R1
(6ES7155-6AU00-0HM0)
• ET 200SP HA IM 155-6 PN HA
(6DL1155-6AU00-0PM0)
• ET 200iSP IM 152-1 PN (6ES7152-1BA00-0AB0)
R1 devices are equipped with two interface mod-
ules compared to S2 devices. If one interface mod-
ule fails, the R1 device can still be reached by the H-
CPUs via the second interface module. Thus, R1
devices have a higher availability than S2 devices.
As of FW version V3.0, the S7-1500H redundant
system supports additional configuration variants:
• Configuration of PROFINET rings with R1 devices
• Configuration of a line topology with S2 devices,
switched S1 devices
• Configuration of a line topology with R1 devices
• Configuration of a combined topology with R1
devices, S2 devices
• Configuration without additional devices
This allows you to connect the S7-1500H redundant
system to almost any network topology and solve
complex automation tasks.
As of FW version V3.0, OB 70 (I/O redundancy error)
is available for the diagnostics of R1 and S2 devices
in S7-1500H systems.
As of FW version V3.0, a new synchronization mod-
ule Sync Module 1 GB FO 40 km is available. The
synchronization module enables a spatial distance
of the two H-CPUs of up to 40 km via optical fibers.
This allows you to use the S7-1500H redundant
system for long tunnel installations.
As of FW version V3.0, the instructions for the data
block functions are supported:
• CREATE_DB (create data block)
• READ_DBL (Read from data block in the load
memory)
• WRIT_DBL (Write to data block in load memory)
• DELETE_DB (delete data block)
