Line: The data is plotted as a Line graph, with squares plotted at each data point.
Point: The data is plotted as squares at each data point.
X-axis projection: The data is plotted as a line graph (no squares). The plot is filled along the X-axis.
Y-axis projection: The data is plotted as a line graph (no squares) with the X and Y data transposed. The plot is filled
along the Y-axis.
The Reference line section lets you configure up to four horizontal lines that can be drawn across the plot. Each line
can be enabled separately, and can have a unique color and position. The position specified for each line is relative to
the values entered in the Low Limit and High Limit fields. If the Limit from PLC box is checked, the reference lines are
referenced to the values entered in the specified register addresses (low limit = value in register address; high limit =
value in register address + 1).
Alarm Bar
The Alarm Bar Object is used to display alarms detected by the Alarm (Event) Log Object. It displays the alarm
message for each current alarm in a single horizontal scrolling line across the Alarm Bar’s display. Only the most
recent alarm appears in the Alarm Bar.
Alarm Display
The Alarm Display Object is used to display alarms detected by the Alarm (Event) Log Object. It displays the alarm
message for each alarm in a table format arranged in chronological order. All current alarms are displayed in the
Alarm Display and are removed from the list once the alarm condition is cleared.
An Alarm Acknowledge function can be enabled, which provides a Write address for the Alarm Display. Each
alarm/event can be acknowledged by touching the message in the Alarm Display. A different color can be assigned for
the Acknowledge status.
An Indirect Window can be configured to popup when the alarm/event is acknowledged to provide additional
information to the operator on how to proceed. The Indirect Window should be placed on the same window as the
Alarm Display. The window number is configured in the Alarm (Event) Log’s Message tab (Write value for Event
Display object) and is written into the Write address assigned in the Event Display.
Event Display
The Event Display Object is used to display alarms or events monitored by the Alarm (Event) Log Object. Events can be
displayed in Real-time or History mode. In Real-time mode, each alarm/event can be acknowledged by touching the
alarm/event in the Event Display. Different colors can be assigned for the Acknowledge and Return To Normal
statuses.
An Indirect Window can be configured to popup when the alarm/event is acknowledged to provide additional
information to the operator on how to proceed. The Indirect Window should be placed on the same window as the
Event Display. The window number is configured in the Alarm (Event) Log’s Message tab (Write value for Event
Display object) and is written into the Write address assigned in the Event Display.
In History mode, alarm/events from previous days can be displayed. The Write address changes to History Control
address, and the value in the History Control register determines which historical data is displayed. When the value in
the History Control register is 0, the data for today is displayed in the Event Display. When the value is 1, the data
from yesterday is displayed, when the value is 2, the data from two days ago is displayed, etc. Use the Option List
configured for “Source of item data: Dates of historical data” to select the day by date.
Check Enable reading multiple histories to display events from more than one day at a time. There are two modes:
With Number of days 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 determines the number of days of data
