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
