 Module is located in a different slot than the one
configured in the ladder logic/AOI
 Processor is not in RUN or REM RUN mode

3.1.2 Non-Scrolling LED Status Indicators
The non-scrolling LEDs indicate the module’s operating status as follows:
LED Label Color Status Indication
APP Red or
Green
OFF The module is not receiving adequate power or is not securely
plugged into the rack. May also be OFF during configuration
download.
GREEN The MVI56E-DNPNET is working normally.
RED The most common cause is that the module has detected a
communication error during operation of an application port.
The following conditions may also cause a RED LED:

The firmware is initializing during startup
 The firmware detects an on-board hardware problem
during startup
 Failure of application port hardware during startup
 The module is shutting down
 The module is rebooting due to a ColdBoot or WarmBoot
request from the ladder logic or Debug Menu
OK Red or
Green
OFF The module is not receiving adequate power or is not securely
