Maximum Number of Nodes per Network based on Topology
• For a network using MRP ring topology, the maximum number of nodes is 64
(consisting of the PNC001 PROFINET Controller(s) plus up to 62 or 63 IO-Devices). If the
ring uses Media Redundancy Protocol, this means one Media Redundancy Manager and
up to 63 clients.
• For a network using MRP ring topology and an Embedded PROFINET IO-Controller as
the MRP Ring Manager, the maximum number of nodes is
• For a network using star topology, the maximum number of nodes configurable is 263
(consisting of up to 8 PNC001 PROFINET Controllers plus up to 255 IO-Devices).
• For a network using star, line topology, or MRP Ring (where the Embedded PROFINET
IO-Controller is not the MRP Ring Manager) the maximum number of nodes
configurable of the system is 264. This may consist of up to eight IC695PNC001
PROFINET Controllers and one Embedded PROFINET IO-Controller (CPL410, CPE400 or
CPE330) plus up to 255 I/O-Devices.

Operating Temperature De-Rating:

The operating temperature range is specified for the module and not the system. As a
guideline, if the module is next to hot neighbor modules on each side the maximum
operating ambient temperature should be de-rated as described below:
• If 100 MB Fiber SFPs installed, then reduce by 5°C
• If Copper SFPs operating at 1 GB, then reduce by 6°C
Introduction
for CPE330/CPE400: 32 (1 MRP Manager and 31 MRP clients)
-
for CPL410: 64 (1 MRP Manager and 63 MRP clients)
-
- for CPE100/CPE115: 9 (1 MRP Manager and 8 MRP clients).
