Robert,
I am located at the PSDF (Power System Development Facility) her in
Wilsonville, AL. back a couple of years ago, we upgraded to an AW51C from
AW51A box (Ver. 4.1). We also have OSI PI system. I thought the A box was
slow, but when we got our C box, it would run fine without PI running, but
when PI was started the C box would crash in about 45 minutes. We had to get
an AW51E box to fix the problem. We did work it out since we had just
upgraded to a C box. I know this probably does not answer your question, but
I thought I would throw this in.
