2 Effective with firmware v9.30, CPE100/CPE115 supports MRP.
In the case of CPE330, with embedded PROFINET activated, it is possible to have five PROFINET Controllers. However, in
3
the rare case of having all 5 PNCs configured on the same LAN, and then invoking redundancy, each CPU is again
restricted to a limit of 4 PNCs (in order to satisfy the overall limit of 8 PNCs per LAN).
GFK-2571N
Four PNC001 maximum. Must be located in main CPU rack. Cannot be
located in a remote node.
CPE330 supports one embedded PROFINET Controller plus up to four
PNC001.
CPE400 & CPE100/CPE115 support one embedded PROFINET Controller.
Since these are standalone CPUs they do not support any PNC001 in their
hardware configuration.
128 max per PNC001 at maximum update interval.
32 max (simplex) or 20 max (Hot Standby Redundancy) per embedded
PROFINET Controller at maximum update interval.
8 max per RSTi-EP CPE100/CPE115 embedded PROFINET Controller.
For limits at shorter update intervals, refer to PROFINET Controller Loading
Limits in Chapter 3.
PNC001 – 63
Embedded PROFINET Controller - 31
Embedded PROFINET Controller CPE100/CPE115
Maximum of 255 simplex or 255 redundant I/O Devices per network,
spread across a maximum of 8 I/O Controllers.
The actual total number of devices supported per network depends on the
topology. For details, refer to Maximum Number of Nodes per Network
based on Topology, below.
Maximum of 255 simplex or 255 redundant I/O Devices per RX3i CPU,
spread across up to four PROFINET Controllers.
Maximum of 8 simplex I/O Devices for CPE100/CPE115.
Eight maximum
Maximum of 128 Kbytes combined input and output memory
Note: RSTi-EP CPE100/CPE115 supports maximum 8 IO Devices so the
combined input and output memory is equivalent to maximum input
/output memory supported by 8 devices.
