Table 4-73 Stored Events - Honeywell VRX180 User Manual

Trend Data 2, 3 & 4
Trend Data 2, Trend Data 3 and Trend Data 4 use the same prompts as in Table 4-72.
Alarms
Alarm data storage consists of a complete log of alarms, including time of occurrence, time of clearing,
value of the alarm parameter, the alarm sense (high, low, etc.) and the batch identification number, if
present. The alarm prompts are: STORAGE MODE, ROLLOVER, ALARM SAMPLES, EXTERNAL
ENABLE, SELECT FILENAME. See Table 4-72 for descriptions.
The number of samples which can be stored in a file (ALARM SAMPLES) can be up to
1600. Depending on your selections, data collection will begin when the first alarm occurs, or when the
first alarm occurs after a batch start.
Events
Event storage consists of a complete log of events including the event title, time of occurrence, the
status or value after the change, and the batch identification number, if present. When event storage is
running, loop and instrument mode events are always stored; discrete input and output events are
stored only if first enabled under those items' program menus (see Sections 4.10 and 4.11).
