When I add a module and configure the system, are the settings initialized?

Generally they are not initialized if the modules are not different from the previous system. However, initialization happens if slots are in the following conditions.

1. Slot replaced with a module of a different model name or style number
2. Slot whose module was removed
3. Slot with a newly installed module
4. Take care, because initialization can result in incorrect settings for MATH, differential calculation, alarm output, and other factors. Take similar precautions when saving in a project.
