Hardware Reset via Node
Switches
The special switch value of 888 allows the user to return the module to its factory
default configuration. The setting of 888 shall reset all local configuration
parameters on the adapter,
The setting of 888 is useful in situations where the user wishes to decommission
an adapter (but may use it again later, e.g., as a spare module), or when the user
wishes to commission a previously-used module that has unknown configuration
parameters.
When the switches are set to 888, upon the next power up, a module shall behave
as follows:
• Return to factory default settings local to the adapter.
• Cease communications on all communication ports.
• The Port Status LED shall transition to blinking red.
• The Network Status LED shall transition to off.
The purpose of the above behavior is to prevent the user from resetting the
module and then never changing the switch setting from 888. Upon the next
power up, the module would simply reset itself again.
Viewing Adapter
Diagnostic Items
If you encounter unexpected communications problems, the adapter’s diagnostic
items may help you or Rockwell Automation personnel troubleshoot the
problem. Adapter diagnostic items can be viewed with any of these drive
configuration tools:
• LCD PowerFlex 7-Class HIM (Diagnostics/Device Items)
• Connected Components Workbench software, version 1.02 or later
• DriveExplorer software, version 2.01 or later
• DriveExecutive software, version 3.01 or later
Flashing Red/
Green
The adapter is performing a self-test. No action required.
Flashing Green The adapter is properly connected, has
an IP address, and is connected to an
EtherNet/IP network but does not have
an I/O connection.
• Place the controller in RUN mode, or apply power to the peer device
that will send I/O.
• Program the controller or peer device to recognize and transmit I/O
or make a messaging connection to the adapter.
• Configure the adapter for the program in the controller or the I/O
from the peer device.
Steady Green The adapter is properly connected and
communicating on the network to a
controller.
No action required.
