Settings Profiles and Profile Triggering
The Settings Profiles are groupings of settings within the control created to allow changing from one group to
another quickly based on internal or external triggers. Additionally, several methods of Triggering a change
from one Setting Profile to another automatically are provided.
Settings Profiles – Settings Profiles are defined as a group of settings in the control that can be selected as
the Active Profile either automatically based on selected triggers, or via SCADA. The Active Profile is defined
as the Settings Profile currently in use providing the parameters the control is operating with. There are eight
Settings Profiles that can be created in the control.
Profile Triggers – Once a trigger has been selected as a trigger for one profile, it is no longer available as a
trigger for the other profiles. Only one trigger can be assigned to a profile with the exception of the SCADA
trigger. Triggers may also be prioritized from 2 to 8 with the exception being SCADA, which is always priority 1.
•
SCADA Profile Trigger
– SCADA can be selected to trigger any profile up to all eight. An Analog
Output DNP point named “SCADAHB Profile Switch” allows the user to change what Settings Profile
is the Active Profile in the control as long as the Heartbeat is active.
• Season Profile Trigger – Each Season Trigger allows the user to set the following parameters:
– Start Date
– End Date – Selecting this date calculates the Number of Occurrences and displays it.
