ET 200SP BU15 BaseUnits

ET 200SP BU15 BaseUnits is the baseline branch for cabinet ET200 projects where terminal arrangement, potential-group layout, and spare strategy still need to be stabilized before the exact base unit is chosen. Within Launch Refresh 2026-03-14, the practical separation comes from terminal layout, potential-group planning, and broad ET 200SP compatibility. Use this branch when the project already points to ET 200SP but still needs a stable cabinet-base family before the exact order code is fixed. For retrofit and spare work, keep the installed footprint and documentation path in view so the baseline ET 200SP choice remains supportable over time. Compare it against shielded and high-feature variants when EMC handling, denser terminations, or more segmented layouts might change the shortlist.
