Note:
Reference Variable: to be used by the PNIO_DEV_COMM logic blocks. The choice defaults
to none. To create a reference variable for the device, use the drop-down list to select
Create. The variable name appears in the Inspector field:
Figure 84: Assigning Reference Variable to IO-Device
IO LAN: (read-only) identifies the LAN of which the IO-Device is a part.
Device Name: this can be edited within the Inspector, or the default name can be used.
Space characters are not permitted.
Device Description: an optional description can be entered for the IO-Device.
IP Address: IP Address for the IO-Device. Default is assigned the lowest value that is currently
available within the automatic IP Address range defined for the LAN on which the device
resides.

Assigning IO-Device Names

After the PNS and third-party IO-Devices on the LAN have been entered the configuration,
the Discovery and Configuration Protocol (DCP) tool in Machine Edition must be used to
assign a name to each IO-Device. This step is required before downloading the configuration
from the PROFINET Controller. Without this step, the PROFINET Controller would be unable
to connect to the devices and deliver their configuration.
The programmer must be connected to the RX3i controller system and the LAN and its
devices must be installed.
Configuration
Note that shorter update periods place higher processing loads on the associated
PROFINET Controller. Refer to above Section, PROFINET Controller Loading Limits. A
PNC001 module can handle heavier loads than an equivalent embedded PROFINET
Controller.
