Ladder logic is required for the MVI69-GEC module to work. Tasks that must be handled by
the ladder logic are module data transfer, special block handling, and status data receipt.
Additionally, a power-up handler may be needed to handle the initialization of the module's
data and to clear any processor fault conditions.
The sample ladder logic, on the inRAx CD-ROM, is extensively commented, to provide
information on the purpose and function of each rung. For most applications, the sample
ladder will work without modification.
