This allow you to move the *.msw file with the *.mbp files to another directory. Thus The *.mbw file will still be able to find the *.mbs files as they are relative to the *.msw. 2006-06-03 Version 4.0.0 - NEW: Grid used to view Modbus values. - NEW: Alt+S, Alt+U, Alt+H and Alt+B used to change display types. - CHG: F8 used to display Poll definition instead of F2.
