Configuration Overview

The Proficy Machine Edition PLC Logic Developer programmer is used to create and download the
configuration for an RX3i PROFINET network and its devices.
System Planning
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 64) is determined by their update rates as shown in
the following calculation:
Maximum Configuration at Each Update Rate
If the configuration exceeds the equivalent of eight devices with 1ms update rates, Machine Edition
will not store the configuration.
