MVI56E-MCMR User Defined Data Types .......................................... 116
Ladder logic is required for application of the MVI56E-MCMR 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 is extensively commented, to provide information on the
purpose and function of each rung. For most applications, the sample ladder will
work without modification.
