Your question is site specific. Unless, for the purpose I'd been using UDS2000 at my shop -- my answer would be useless. Suggest, you look into the documentation of the PROC(s) in which this program is called.
Just for a note -- usually, in a crude sense, whenever there is a need of balancing between interfacing systems this program is used under the heading "UNITECH AUTOMATED CONTROL". So it's a program used for Unitech Procedures. It's a copyright material if you need further information get in touch with Unitech Support people at your shop or the people who support this there.
Hope this helps.
