Assigning IO-Device Names

After the RX3i CEP and other IO-Devices on the LAN have been entered into the
configuration, the Discovery and Configuration Protocol (DCP) tool must be used to assign
a name to each I/O Device. The name of each device on the LAN must match the hardware
configuration in the IO-Controller. This step is required before downloading the
configuration from the PROFINET IO-Controller, or the PROFINET IO-Controller will be
unable to connect to the devices and deliver the device's configuration.
The DCP tool must be connected directly to the PROFINET I/O LAN. The DCP tool allows you
to display an identification pattern on an IO-Device. This can be helpful to distinguish
devices apart when all are at factory default settings.
The DCP tool supports issuing a reset command to an IO-Device. A reset clears the device
name and sets other nonvolatile settings such as IP, subnet, and gateway to the factory
defaults.
4.6 After the Configuration is Stored to the I/O
Controller
For complete instructions, refer to the documentation for the IO-Controller and the
PROFINET I/O configuration tool.
After successfully processing and applying its configuration data, the IO-Controller transfers
the configuration for remote IO-Devices over the PROFINET network.
An IO-Controller delivers configuration to an IO-Device when it establishes a connection
with the IO-Device. If all connections are lost, the IO-Device retains the most recent
