Description
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.
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.
The Media Redundancy Protocol enables the configura­
tion of redundant networks. Redundant transmission
links (ring topology) ensure that an alternative commu­
nication path is made available if a transmission link fails.
Within the PROFINET ring, the R-CPUs assume the role of
the MRP Manager following appropriate project configur­
ation and all other devices in the ring assume the role of
the MRP clients.
The process MRP interconnection is an enhancement of
MRP and allows redundant coupling of two or more rings
with MRP in PROFINET networks. MRP interconnection is -
like MRP - specified in the standard IEC 62439-2 (Edition
3).
PROFIenergy is a PROFINET-based data interface for
switching off consumers centrally and with full coordina­
tion during pause times regardless of the manufacturer
or device type. Through this, the process should only be
provided with the energy that is absolutely required.
Most of the energy is saved by the process. The
PROFINET device itself only contributes a few watts to
the savings potential.
