Data Logging Chapter 7

Reading Data from the Event Log by Using Communication

The Event Log uses the indexed read method. The

Event Log

Configuration/Read-back Record Select

table is the Read-back Select

table and the

Event Log Results

table is the Results table. You may

select among a number of read-back options for the Event Log.

0 = Auto-increment / start at beginning of log

1 = Auto-increment / start at end of log

2 = Auto-decrement / start at end of log

3 = Point to the beginning of log

4 = Point to the end of log

5 = Index to the next record

6 = Index to the previous record

Indexing occurs after each read of the Results table.
Only mode 0, 1, and 2 are supported by DF1 and remote I/O
communication.

The

Event Log Results

table is a read-only data table containing 14

(M4, M5), 17 (M6) or 18 (M8 only) integer elements as follows:

Reserved: returns 0

Event record internal identifier: An incremental number assigned
to each new event. See below

Timestamp: event timestamp expressed in four-element
timestamp format (see below)

Event type: see Event Codes on

page 144

Event command code: see Event Codes on

page 144

and Status

Error Codes on

page 146

Setpoint type, evaluation condition, level, action/release delay,
and action: if event is a setpoint, these elements return
additional information about the setpoint. The Setpoint level,
expressed in integer/exponent format, records the worst-case
value of the setpoint parameter

Sustain limit timer (M6, M8 only): time the setpoint parameter
exceeded the limit, expressed in integer/exponent format

Capture identifier (M6, M8 only): identifies oscillograph or
transient capture number if applicable
