Ladder logic is required for application of the MVI69-EGD 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.
3.1 Adding the Module to an Existing CompactLogix Project
Important: The MVI69-EGD module has a power supply distance rating of 2 (L43 and L45
installations on first 2 slots of 1769 bus)
If you are installing and configuring the module with a CompactLogix processor,
follow these steps. If you are using a MicroLogix processor, refer to the next
section.
