Configuring the Embedded PROFINET IO-Controller (PNC)

4.2
This section explains how to configure the RXi PNC and its IO-devices in a PACSystems RXi
Controller system.
The Proficy Machine Edition programming software is used to create and download the
configuration for an RXi PROFINET network and its devices. Additional information about RXi
configuration is available in the Proficy Machine Edition online help.

System Planning for PROFINET Networks

Device Ownership
Note that all modules in an IO-Device must belong to the same PROFINET network. That is,
they are all owned by the same PNC. Modules on an IO-Device cannot be split
between PNCs.
PNC Loading Limits
To prevent overloading of the PNC, the maximum number of IO-Devices that can be
configured is limited to the equivalent of eight devices with update rates of 1ms.
Devices configured with a longer update periods present smaller data loads to the PNC.
For example, a device with an update rate of 2ms is equivalent to ½ device at 1ms.
The maximum number of devices allowed (up to
