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-SIE 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
plugged into the rack.
GREEN The module is operating normally.
RED The module has detected an internal error or is being
initialized. If the LED remains RED for over 10 seconds, the
module is not working. Remove it from the rack and re-insert it
to restart its internal program.
ERR Red OFF The battery voltage is OK and functioning.
ON The battery voltage is low or battery is not present. Allow
battery to charge by keeping module plugged into rack for 24
hours. If ERR LED still does not go off, contact ProSoft
Technology, as the battery is not a user-serviceable item.
