Replace unit		A user-defined unit can be replaced by a unit from the ACRON units system. : `The units used in a plant, such as [KWh] or [cbm], can be replaced by the ACRON units [kWh] and [m³].` NoteWhen updating, all units used in the plant that are not found in the ACRON units system are created as user-defined units under 'Miscellaneous units'.These units can be moved to the appropriate category as appropriate, and assigned a factor/offset (relative to the base unit).
Event		Events are defined by start and stop conditions, as well as a minimum duration between those two values.
Event step		Steps are subevents within an event. They are likewise defined by start and stop conditions, as well as a minimum duration between those two values.

Category		ACRON Base unit under which the fractions and multiples of the respective unit are grouped.
Category		User-defined Base unit under which the fractions and multiples of the respective unit are grouped.
Key figure		The basic structure of a key figure corresponds to that of a standard calculation variable. A key figure is created on the basis of the selected key figure template. This template assigns default values to all required properties of the key figure.
Key figure template		ACRON Key figure templates form the basis for special calculation variables termed key figures. They are not editable.
Key figure template		User-defined unit Key figure templates form the basis for special calculation variables termed key figures.
Configuration check		Check of the complete configuration

Unused variables		Variables with enabled measured value archiving without assigned process variable... Display of all external variables for which measured value archiving is enabled, but with no process variable assigned to them, with the facility to delete single ones or all. Variables with enabled service recording without assigned entity...

Language...		The selection of the program language defines the language in which the ACRON user interface and the Help are displayed.
Provider		The ACRON Provider is responsible for reading the measured data from the control system/PLC and saving them to the external variables.
Standard calculation variable		This type essentially corresponds to the auto and manual variables. The value basis for the calculation is defined, as is/are the compression level(s) for which the result is to be delivered. The calculation results are stored on a physical medium.
Temporary calculation variable		The values of these calculation variables exist only temporarily, and are not stored. They serve primarily to make complex calculations simpler in format. To do so, individual calculation steps are transferred out to temporary calculation variables, which are then incorporated into the actual (standard) calculation variable.
Live calculation variable		This type enables calculations to be performed using values of external process variables. Multiple analysis levels can be selected for the data basis. No compression can be selected – the data basis and calculation result always belong to one compression level.
