4.2 LED Status Indicators: Front of MVI56 Module
The LEDs indicate the module’s operating status. The module has two sets of
LED status indicators:

MVI56 Module Status LEDs on the front of
the module near the top

PROFIBUS Master Status LEDs behind the
door on the front of the module.
4.2.1 Module Faceplate Status Indicators
Indicator Color Status Indication
CFG Green ON Configuration/Debug Port is active
OFF Configuration/Debug Port is inactive
P1 Not Used
P2 Not Used

STATUS
Amber ON Configuration Error: This LED is illuminated when the
PROFIBUS and module CRC values do not match
between input/output blocks.
Verify that the values match the values generated with
the Calculate Checksums button in ProSoft
Configuration Builder. If they do not match, you must
manually change the values at the appropriate address
locations listed in the Input and Output block definitions
in this manual.
OFF Normal operation.
BP ACT Amber ON The LED is ON when the module is able to
communicate over the backplane.
OFF The LED is OFF when the module is unable to
communicate with the processor. The processor is
either absent or not running.
BATT
Red OFF The battery voltage is OK and running.
ON The battery voltage is low or the battery is not present.
The battery LED will illuminate briefly upon the first
installation of the module or if the unit has not had
power for an extended period of time. This behavior is
normal; however, should the LED come ON in a
working installation, please contact ProSoft
Technology.
OK Red/
Green OF The card is not receiving any power and is not securely
plugged into the rack.
GREEN The module is operating normally.
RED The program has detected an error or is being
configured. If the LED remains RED for over 10
seconds, the processor program may be incompatible
with the module. Check the module version (page 18)
and mode (page 20) (Legacy or Flex) to determine the
correct sample ladder logic. Remove the card from the
rack and re-insert the card to restart the module’s
program.
