user-defined name that is associated with a given data point format description (for example,
SNVT_switch or SNVT_temp). Nicknames are used in a type translation rule to reference the
selected input and output points. Once you have created and used a nickname do not modify it
because doing so breaks all other existing Type Translators that use the same translation. By
default, a data point’s nickname is the data point portion of its full network name. For example, a
data point with a name of “Net/LON/iLON App/VirtFb/nvoLevDisc” has a default nickname of
“nvoLevDisc”.

5. Click Back to return to the Type Translator: Configure Web page.
Note: If you are using a scalar-based translation, the input and output points must be both be of an
integral or floating-point type.
Selecting or Creating a Type Translation
You can select a pre-defined type translation, or you can create a custom type translation. Once you
create a custom type translation, you can select it and re-use it for other translations.
If you select a type translation that is not compatible with the selected input and output points, a “rule
is incompatible” warning appears just above the tree/application frame. You can hide incompatible
type translations by selecting the Hide Incompatible Rules check box directly below the Rules icon.
Selecting a Pre-Defined Type Translation
The Type Translator includes 15 pre-defined Type Translator rules that you select from the list below
the Rule icon. You can select a pre-defined rule provided that it is compatible with the selected input
and output points. Once you create a custom rule-based translation, it is added to the list of defined
translations that you can select.
The default translation, Copy Input DP to Output DP, is a scalar-based translation that directly
converts the value of the input point directly to the output point without any scaling. Of the other 14
pre-defined translations, which are all rule-based translations, 11 are for converting L
ON W ORKS data
points and 3 are for converting M-Bus data points. The following subsections describe each the 11
pre-defined rule-based translations that you can use to convert L
ON W ORKS data points. See
