Typical conversion link usage

The most expected usage of a conversion links is to support a link between a “status type” numeric or boolean to a “simple type” numeric or boolean, or vice versa. Figure 1 shows an example.

Figure 1. Example link from status type to simple type (statusBoolean to Boolean)

In the example above, the statusBoolean “out” of a BooleanWritable (Fan control) point is needed to enable/disable several history extensions, where the “Enabled” property is a simple boolean type. Before AX-3.6, this required an intervening “StatusBooleanToBoolean” component. However, now you simply link between the two dissimilar slots, as allowed in the Link editor.

Figure 2 shows another example, this time linking from a simple data type to a status type.

Figure 2. Example link from simple type to status type (integer to statusNumeric)

In the example above, the integer “Change Of State Count” slot value of a DiscreteTotalizerExt of a BooleanWritable is needed as an input in a Math component, say an “Add” component. Before AX-3.6, this required an intervening “IntegerToStatusNumeric” component. Again, now you can simply link the two slots, as allowed in the Link editor.
