RSTI-EP PROFINET I/O Controller User Manual Section 1
GFK-2571R May 2021
Introduction 7
Specification Description
Max MRP Clients when
configured as MRP Manager PNC001 – 63
Embedded PROFINET Controller CPE330/CPE400 – 31
Embedded PROFINET Controller CPL410 – 63
Embedded PROFINET Controller CPE100/CPE115 2 – 8
IO-Devices per Network 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.
IO-Devices per RX3i CPU Maximum of 255 simplex or 255 redundant I/O Devices per RX3i
CPU, spread across up to four PROFINET Controllers.
3
IO-Devices per RSTi-EP CPU Maximum of 8 simplex I/O Devices for CPE100/CPE115.
IO-Controllers per Network Eight maximum
Input and output memory
per IO-Controller
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.
Number of PROFINET Slots
per device 256
Number of PROFINET Sublots
per slot 256
Number of PROFINET
Submodules per RX3i CPU 2048
Programmer Limits
Number of IO-Controllers 128 (32 RX3i CPU targets × 4 IO-Controllers per RX3i CPU)
Number of IO-Devices 2048 (128 per network × 16 PROFINET networks)
Total number of devices 2176 (does not include backplanes, power supplies, or I/O modules)
For product standards, general operating specifications, and installation requirements,
refer to the PACSystems RX3i System Manual, GFK-2314.
2
Effective with firmware v9.30, CPE100/CPE115 supports MRP.
3 In the case of CPE330, with embedded PROFINET activated, it is possible to have five PROFINET Controllers. However, in 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).
