Ladder logic is required for managing communication between the MVI69E-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 the module’s

database and may clear some processor fault conditions.

The sample Import Rung with Add-On Instruction (from the ProSoft DVD or

www.prosoft-technology.com) 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.
