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.
