Ladder logic is required for managing communication between the MVI69L-MBS
module and the CompactLogix processor. The ladder logic handles tasks such
as:
 Module backplane data transfer
 Special block handling
 Status data receipt
Additionally, a power-up handler may be needed to initialize th
e module’s
database and may clear some processor fault conditions.
The sample Import Rung with Add-On Instruction is extensively commented to
provide information on the purpose and function of each user-defined data type
and controller tag. For most applications, the Import Rung with Add-On
Instruction works without modification.
