Converter properties

Most conversion links have no properties under the link’s Converter component. This is true for all conversion links between “like” data types, that is, status type-to simple and vice versa. However, conversion links that transform values like string to boolean or numerical, or the reverse (to string) may have one or more Converter properties.

The image below shows one example.

Figure 69. Example Converter with properties (Status Boolean To Number)

The example above reflects default values for a link made from a statusBoolean slot (in this case, “out” of a BooleanWritable) to an Integer slot (in this case, “Duty Cycle” of a MultiVibrator). The converter type automatically used is “Status Boolean To Number”.

Expanding the Converter component in the Edit Link dialog reveals two properties:

True Value — default value of 1
False Value — default value of 0

The duty cycle range of a MultiVibrator is from 0 to 100, so defaults here are not typically appropriate.

Figure 70. Example Converter properties edited to non-default values

In this example, converter properties were edited to true at 75, and false at 25, as shown in the figure above.

In cases where the link’s slot target (To) data type is string or statusString, the Converter property, if present, is typically “Format”. If a default “%.%” value, this means it is BFormat (Baja Format).

Figure 71. Example Format property of “Boolean To String” Converter edited from default “%.%”

The figure above shows the static text “Enabled:” prepended on the default %.% Format property value of a “Boolean to String” link Converter.
