Customer benefits
You can download a modified user program into the
R/H CPUs in the RUN-Redundant system state.
Advantage: The redundant system will remain consist­
ently in the RUN-Redundant system state during the
change to the user program. The system state will not
switch to RUN-Rolo or SYNCUP.
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.
The "Switched S1 device" function of the CPU enables
operation of standard IO devices in the S7-1500R/H
redundant system.
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 advantages:
• 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 pri­
or to actual commissioning
• Recording of current values within individual
executed loops
• Using breakpoints for program validation is also
possible in SCL or STL networks within LAD/FBD
blocks.
PID controllers are built into all R/H‑CPUs as standard.
PID controllers measure the actual value of a physical
variable, for example, temperature or pressure, and
compare the actual value with the setpoint. Based on
the resulting error signal, the controller calculates a
manipulated variable that causes the process value to
reach the setpoint as quickly and stably as possible.
The PID controllers offer you the following advantages:
• Simple configuration and programming through
integrated editors and blocks
• Simple simulation, visualization, commissioning
and operation via PG and HMI
• Automatic calculation of the control parameters
and tuning during operation
• No additional hardware and software required
cution in the S7-1500R/H redundant system and to
quickly identify, accurately locate, and correct errors.
