CONTACT INPUTS AND OUTPUTS COLUMNS
The columns headed "Outputs" and "Inputs" show the states of the first eight outputs and the first
eight inputs. (These are either the physical outputs and inputs or the mirrored-bit outputs and
inputs. The EVE 1 L M shows the long form of the event report with TMB1...TMB8 and
RMB1...RMB8 occupying the last columns of the event report.)
Since there are only four columns under each heading, the outputs and inputs are paired in
groups of two. If an output is asserted in the first column, a "1" or "2" appears in the column to
indicate which output is asserted. If both inputs are asserted, a "B" would appear under the
associated column. A period indicates deassertion. All outputs and inputs are assignable. The
most important output functions should be assigned to the first eight outputs since they are the
only outputs displayed in the standard event report. Functions assigned to outputs above eight
are not displayed on the event report but are available in the computer event report format. The
following list shows the contents of these columns.
