Please contact your regional ABB support office.
Even with the aforementioned 64-bit version of System 800xA (which run in WOW64 mode i.e. NOT the genuine 64 bit mode) most (all?) applications are still using the 32-bit memory address space, i.e. they have not been "large address aware" (http://msdn.microsoft.com/en-us/library/wz223b1z.aspx). This may change in a future version.
The current benefit with 64-bit version is:
- compatibility with today's hardware and OEM loads of Microsoft Windows.
- make use of more than 3.5 RAM in a computer
Still, most processes can not grow larger than 2 GB just as it was in 32-bit Windows.
