Where can I find information?
Download modified user
program in RUN-
Redundant system state
You can download a modified user program into the
R/H CPUs in the RUN-Redundant system state.
Advantage: The redundant system will remain con-
sistently in the RUN-Redundant system state during
the change to the user program. The system state
will not switch to RUN-Solo or SYNCUP.
S7-1500R/H System Manual

Backing up the configura-
tion of the S7-1500R/H
redundant system in
runtime
You do not have to interrupt the process during a
backup while the plant is running.
Uninterrupted plant operation avoids high restart and
material costs.
Switched S1 device
The "Switched S1 device" function of the CPU ena-
bles operation of standard IO devices in the S7-
1500R/H redundant system.
Testing with breakpoints When testing with breakpoints, you run a program
from breakpoint to breakpoint in the STARTUP
(startup OB) or RUN-Solo system state. Testing with
breakpoints provides you with the following ad-
vantages:
•
Testing SCL and STL program code with the help
of breakpoints
•
Localization of logic errors step by step
•
Simple and quick analysis of complex programs
prior to actual commissioning
•
Recording of current values within individual exe-
cuted loops
•
Using breakpoints for program validation is also
possible in SCL or STL networks within LAD/FBD
blocks.
