Acknowledgment
: a confirmation that you have received and noticed an alarm.
Alarm
: an alarm is always created based on a channel and monitors the channel’s value according to
set conditions and limits. A‑alarm has a red indicator and B‑alarm has a yellow indicator. In addition
to these, you can choose to give an alarm a priority from C‑Z and they have a blue indication.
Alarm groups
: manages alarm sendouts and makes it possible to create features for multiple alarms
at the same time.
Application
: builds the functions in the Ultra. An application contains graphical programming or
script and resources such as channels, parameters, curves, all of which are visible in the graphical
programming. Overviews and summaries are part of an application. An application can contain other
applications, which are subapplications. In the graphical programming, an application is represented
as a box with inputs and outputs. You can create an application template, which can be useful if you
want to create similar applications.
Application backup
: a backup with application templates.
Change history
: a log that gives an overview of the changes made by users. Includes a selection of
resources in the Ultra.
Channels
: handles all the variable data in the unit. Channels are viewed in overviews and summaries
and are logged and monitored by alarms. Channels are used for logs and alarm.
Coils
: this is a type of a Modbus register. One coil is a 1 bit word.
Components
: primitive function blocks in the graphical programming. Connect these with other re‑
sources in order to create programs. They exist only in the graphical programming and cannot be
reached from other parts of the system.
Curves
: a table that is presented as a configurable curve. Curves are used by controllers to do things
like converting an outdoor temperature into a flow temperature.
Events/Errors
: a type of alarm that is created by the system. It notifies you when something is wrong
in the system that may prevent the unit from functioning.
Expansion modules
: used to add more inputs and outputs with different features and communicates
automatically with the Ultra. You can connect an expansion module and the system will recognize it
and its features.
External units
: different types of units that an Ultra can exchange information with, as a master. They
can be used for more inputs/outputs, meters and more. For example, Modbus and M‑bus units can be
connected as external units.
