Description
There are two duplicate CPUs that synchronize their data
via two duplex fiber-optic cables, which connect the
CPUs directly to each other via plug-in synchronization
modules. If one of the CPUs fails, the other CPU retains
control of the process.
The system automatically generates the messages for the
system diagnostics and outputs these messages via a
programming device/PC, HMI device or the integrated
display. System diagnostics information is also available
when the CPUs are in operating state STOP.
Trace functionality supports you in troubleshooting
and/or optimizing the user program.
You record device tags and evaluate the recordings with
the trace and logic analyzer function. Tags are, for
example, drive parameters or system and user tags of a
CPU.
Trace and logic analyzer functions are suitable for monit
oring highly dynamic processes.
Note: Note that the S7-1500R/H redundant system sup
ports recording of measurements. However, saving the
measurements to the SIMATIC memory card is not sup
ported.
IO-Devices with S2 system redundancy enable uninter
rupted operation during a primary backup switchover.
If the role of the CPUs changes, the new primary CPU
takes over the PROFINET IO communication.
IO devices with R1 system redundancy are equipped with
two interface modules compared to S2 devices.
If one interface module 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.
The switched S1 device function of the CPU enables
operation of standard IO devices in the S7‑1500R/H
redundant system.
RT prioritizes PROFINET IO frames over standard frames.
This ensures the required determinism in the automation
technology. In this process the data is transferred via pri
oritized Ethernet frames.
