What are the customer benefits?
The active backplane bus provides you with the
following advantages with the S7-1500H redundant
system:
• Reaction-free removal and insertion of CP 1543-
1 communications processors in the RUN-
Redundant system state.
• Module reserves (CP 1543-1) can be kept ready
for later use.
The active backplane bus can be used with H-CPUs
from firmware version V3.1.
You can find more information on the active back-
plane bus (e.g. installation, configuring, technical
specifications) in the Active backplane bus
(https://support.industry.siemens.com/cs/de/de/view
/109778694/en) Equipment Manual.
The active backplane bus can be ordered as an ac-
cessory/spare part.
The IE/PB LINK HA connects PROFINET IO and
PROFIBUS DP as a gateway. This enables the IE/PB
LINK HA to access all DP devices connected to the
lower-level PROFIBUS network.
The IE/PB LINK HA supports up to 64 DP devices.
In the redundant S7-1500R/H system, the
IE/PB LINK HA is integrated into the PROFINET net-
work as an S2 device.
As of firmware version V3.1, the OB 83 (pull/plug
interrupt OB) with additional events is available for
the S7-1500R/H redundant system:
• Configured I/O module inserted in the central
configuration, with return of redundancy
• Configured I/O module inserted in the central
configuration, with return of redundancy, but
with error
• Configured I/O module removed in the central
configuration, with elimination of redundancy
As of firmware version V3.1 the S7-1500R/H redun-
dant system supports data logging.
With data logging, you can save process values
from the user program in a file, the data log. The
data logs are saved on the SIMATIC Memory Card in
CSV format and stored in the "DataLogs" directory.
Data logs are created and modified using the asyn-
chronous "data logging" instructions. Data logs from
the S7-1500R/H are loaded via the Web API of the
Web server.
