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.

Normal operation.

The LED is ON when the module is able to
communicate over the backplane.

The LED is OFF when the module is unable to
communicate with the processor. The processor is
either absent or not running.

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

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 Determining the Firmware
Version of the MVI56-PDPMV1 Module (page 15) and
Determining the Module Mode (LEGACY or FLEX)
(page 18) (Legacy or Flex) to determine the correct
sample ladder logic. Remove the card from the rack
and re-insert the card to restart the mo
