Ladder logic is required for the MVI71-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.
