CONFIGURING DATA TAGS
EDITING FLAG TAGS
• The Tag Off property is used to define the color pair to be used to display the tag
when it is in the off state.
THE ALARMS TAB
The Alarms tab of a flag variable or formula contains the following properties...
• The Event Mode property is used to indicate the logic that will be used to decide
whether the alarm should activate. The tables below list the available modes.
MODE
Active On
Active Off
ALARM WILL ACTIVATE WHEN…
The tag is true.
The tag is false.
The following modes are only available when a setpoint is defined…
MODE
Not Equal to SP
Off When SP On
On When SP Off
Equal to SP
ALARM WILL ACTIVATE WHEN…
The tag does not equal its setpoint.
The tag does not respond to an ON setpoint.
The tag does not respond to an OFF setpoint.
The tag equals its setpoint.
• The Event Name property is used to define the name that will be displayed in the
alarm viewer or in the event log as appropriate. Crimson will suggest a default
name based upon the tag’s label, and the event mode that has been selected.
• The Trigger property is used to indicate whether the alarm should be edge or
level triggered. In the former case, the alarm will trigger when the condition
specified by the event mode first becomes true. In the latter case, the alarm will
continue in the active state while the condition persists. This property can also be
used to indicate that this alarm should be used as an event only. In this case, the
alarm will be edge triggered, but will not result in an alarm condition. Rather, an
event will be logged to the Master’s internal memory.
