Chapter 1. Introduction
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 CPE330/CPE400: 32 (1 MRP Manager and 31 MRP clients)
o
for CPE100/CPE115: 9 (1 MRP Manager and 8 MRP clients).
o
•
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 (CPE400 or
CPE330) plus up to 255 I/O-Devices.
