EN–221
How Results of the Evaluations Are Reported
The ACCESS 9360 reports evaluation data in register entries and
alarm log entries. Table C–2 describes the register entries for the
evaluation data.
Log entries for the evaluation data include:
• Onboard alarm log entry for diagnostic alarms: When the
status of an area of evaluation is outside the range of acceptable
values, an entry is made in the on-board alarm log. This entry
provides notification of the exception for a specific area of
evaluation. This notification is reported only in WinPM.Net and
does not appear on the local display.
• Onboard alarm log entry for alarms: ACCESS 9360 alarms are
used to perform some of the evaluations. If an onboard alarm log
is enabled, an entry will be made in the on-board alarm log when
any of these alarms pick up or drop out.
NOTE: Enabling EN50160 evaluation does not guarantee that the
onboard alarm log is enabled or properly configured to record these
events. Also, when you enable EN50160 evaluation, you do not
automatically configure onboard data logging or waveform capture
files. You should consider your requirements and configure these
files and the event captures triggered by the various alarms to
provide any additional data that would be helpful to diagnose or
document an exception to this standard.

Register
Number
Description
3910
Summary bitmap of active evaluations that reports which
areas of evaluation are active in the ACCESS 9360.
3911
Summary bitmap of evaluation status that reports the
pass/fail status of each area of evaluation.
Portal registers
Detail bitmap of evaluation status that reports the pass/fail
status of the evaluation of each individual data item.
Detailed data summary information is also available for
each of the evaluations for the present interval and for the
previous interval. You can access this data over a
communications link using Modbus block reads of “portal”
registers. Refer to “Evaluation During Normal Operation”
on page 222 for additional information.
