3 Ladder
Logic
Ladder logic is required for application of the MVI46-N2 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.
