Notes on Available PROFINET Controllers

Each PROFINET I/O Network is controlled by one or more PROFINET I/O Controllers.
PROFINET I/O Controllers may be Emerson products or third-party products.
Emerson offers the following PROFINET Controllers:
•
•
•
•
Each of the RX3i PROFINET Controllers mentioned above can control a PROFINET I/O
Network containing PROFINET Scanners supplied by Emerson or by third-party vendors.
Many vendors also supply I/O devices that connect directly to the PROFINET network.
For PROFINET Controller product details, refer to the PACSystems RX3i PROFINET Controller
User Manual, GFK-2571.

Operations of the PROFINET Scanner

The RX3i PROFINET Scanner (PNS) is the head-end unit responsible for monitoring and
controlling I/O modules installed in its RX3i I/O rack. All PROFINET communications are
passed between the PROFINET I/O Controller and the PNS. The PNS is one type of IO-Device
the PROFINET I/O Controller expects to encounter. Other third-party IO-Devices may also
be present on the PROFINET network.
A PNS will normally be present on a PROFINET network controlled by an RX3i PROFINET
Controller (PNC). However, it is possible to use a PNS in conjunction with any qualified
PROFINET I/O Controller.
The RX3i PNS performs the following operations:
•
•
•
IC695PNC001: this is an RX3i rack-based intelligent module located in a slot of the
host RX3i CPU rack. The host CPU may be equipped with a maximum of four
IC695PNC001 modules.
The IC695CPE330 RX3i CPU provides an optional embedded PROFINET Controller.
To utilize this feature, LAN2 must be configured as a PROFINET Controller. In
addition, the IC695CPE330 may host a maximum of four IC695PNC001 modules in
its CPU rack.
The IC695CPE400 and IC695CPL410 RX3i CPUs both provide an optional embedded
PROFINET Controller. To utilize this feature, LAN2 must be configured as a PROFINET
Controller. Since these are Rackless CPUs, they cannot host any IC695PNC001
modules.
The EPSCPE100 and EPSCPE115 are RSTi-EP Standalone CPUs. They provide an
optional embedded PROFINET Controller.
Consumes PROFINET IO-Device configuration from the PROFINET IO-Controller over
the PROFINET network and applies it to its modules.
Scans input data from each module it manages and produces that data to the
PROFINET IO Controller.
Consumes the output data that it receives from the PROFINET IO-Controller and
applies it to each module it manages.
