Assigning Io-Device Names; After The Configuration Is Stored To The I/O Controller - GE PACSystems RX3i User Manual

Chapter 4. Configuration

4.5 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 configuration received since it was last powered
up. If a module has not been configured since being powered up, it remains in its hardware default condition.
When the connection(s) are re-established and a configuration is sent to the IO-Device, and the configuration
of a module has changed, the I/O Device applies the new configuration.
If there are differences between the expected, configured modules and the actual modules present in the RX3i
CEP Carriers when a connection is established, the RX3i CEP indicates differences back to the IO-Controller.
Refer to Chapter 6, Diagnostics.
