ControlNet-to-DeviceNet Linking Device 

1788-5.2B - October 1999

Module STATUS LED

The Module Status LED indicates whether the CN2DN is powered, configured, 
and operating properly. Table A shows how to interpret the Module Status LED 
states.

Standby state (flashing green) indicates the CN2DN module has passed all self 
tests and is ready to operate, but is not configured.

Operational state (steady green) indicates the CN2DN module has left standby 
state because the necessary network configuration has occurred.

Linking Activity LED

The Linking Activity LED indicates the rate of traffic through the bridge. Table B 
shows how to interpret the Linking Activity Status LED states.

Table A Interpretation of the Module Status LED

LED State

Meaning

Off

No power to device

Flashing green

Standby state

Steady green

Operational state

Flashing red

Major recoverable fault

Steady red

Major unrecoverable fault

Table B Interpretation of the Linking Activity LED

LED State

Meaning

Off

No traffic

Flashing green

Traffic present (flash rate reflects amount of traffic)

Flashing red and green

Module is running boot code only (reduced 
functionality code only for FLASH upgrading)
