Ladder logic is required for managing communication between the MVI69L-
MBTCP 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 the 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 will work without modification.
