Figure F.1 SEL-787 Predefined Reports
There are 12 report control blocks, six buffered reports and six unbuffered. For
each report control block, there can be just one client association, i.e., only
one client can be associated to a report control block (BRCB or URCB) at any
given time. The number of reports (12) and the type of reports (buffered or
unbuffered) cannot be changed. However, by using
ACSELERATOR Architect,
you can reallocate data within each report dataset to present different data
attributes for each report beyond the predefined datasets. For buffered reports,
connected clients may edit the report parameters shown in Table F.4.
