18 SmartGuard 600 Controllers
Publication 1752-IN001C-EN-P - January 2009
Alphanumeric Status Display
The controller’s alphanumeric display provides information about the module’s
status. Under normal operating conditions, the display shows the node address of
the module, 00…63 in decimal format. If the controller is operating in a standalone
configuration (not networked), the display shows ‘nd’. The display flashes when
the controller is self-testing, configuring, or in Idle mode. If a fault exists, the
display alternates between the error code and the node address where the error
occurred. If a fatal error has occurred, the display shows the error code only.
When the service switch is pressed, the display shows the controller’s
safety-configuration signature two digits at a time. The configuration signature can
also be viewed on the Safety tab of the Controller Properties dialog box in
RSNetWorx for DeviceNet software. You can use the configuration signature to
verify that the program and configuration of the controller has not been changed.
When the IP address display switch is pressed for 1 second or longer, the display
shows the EtherNet/IP address that is set. The error code ‘n4’ is displayed if an error
occurs in the EtherNet/IP configuration.
