to display (including the starting day). If three days are selected, but only two event files are included within the
three day period, only two event files will be displayed.
With Index of the last history selected, the value entered in the History control register determines the starting
day (most recent, where 0 = today) and the value in the History control register + 1 is the number of event files to
display. This setting is not dependent on the date and the Event Display will display the designated number of
event files from most recent to oldest.
 The Event Display can display up to 4MB of historical data. If the combined file size of the selected historical
data exceeds 4MB, the most recent data is displayed and the oldest data beyond 4MB is not displayed.
Select Enable event management to control which events to display or hide, and allow users to delete selected
events.
Control address 0 = All events are displayed.
1 = Confirmed events are hidden.
2 = Returned to normal events are hidden.
3 = Confirmed and returned to normal events are hidden.
Control address + 1 1 = Users can delete selected events in real-time mode.
Alarm (Event) Log
The Alarm (Event) Log Object is used to configure alarms and events. Select one of the History files checkboxes to
save alarm/event files in HMI memory or to an SD card or USB flash drive. This is used when an Event Display is
configured for History mode. The Preservation limit lets you limit the number of history files to save. A new file is
created each day with the filename EL_yyyymmdd.evt where yyyy=year, mm=month, and dd=day. For example, the
file for June 12, 2010 would be EL_20100612.evt.
Click the New button to create a new alarm/event. An alarm/event can be triggered by a bit or a word. The
Notification field can be configured to set or clear a bit when the alarm is triggered.
The Message tab allows you to enter a message that will appear in the Alarm Bar, Alarm Display, or Event Display
when the alarm/event is triggered. The Write value for Event Display object is used to enter a window number that is
written to the Write address configured in the Event Display object. This window number is used by an Indirect
Window configured to popup when an alarm/event is acknowledged.
For HMI5000 models with the audio line-out option, a sound can be played when the alarm/event is triggered. Click
the Enable button and select a sound from the Sound Library.
The WATCH addresses can be used to display the data in up to four registers in messages. Click the Syntax button to
see how to configure the message to display the data.
Data Transfer (Trigger-based)
The Data Transfer (Trigger-based) Object is used to transfer word-based data from the specified Source address(es) to
the specified Destination address(es). This can be used to transfer data from one device to another.
The Source and Destination address fields define the starting addresses, and the No. of words field specifies how
many consecutive addresses are transferred. The data transfer can be triggered by touch (Touch trigger mode) or by
an external or internal bit (External trigger mode).
