3 Ladder Logic

In This Chapter

 Module Data .......................................................................................... 28

 Adding the Module to an Existing Project .............................................. 31

Ladder logic is required for application of the MVI46-MCM module. 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 ProSoft Solutions 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.
